Transphorm Expands Second Generation Portfolio with Lower On-Resistance TO-220 650V GaN FET
Posted: 2016-11-11
New Device Brings Greater Design Flexibility While Enabling Bridgeless Totem-Pole PFC Designs

Transphorm Inc., a leader in the design and manufacturing of JEDEC-qualified 650V GaN (gallium nitride) semiconductors, today announced its latest portfolio addition: the TPH3212PS. Available in a TO-220 package, the device has an on-resistance of 72 mOhms (mΩ) and targets AC to DC and DC to AC power supplies. When used inside the former, the TPH3212PS—along with its family members—makes implementing bridgeless totem-pole power factor correction (PFC) designs possible.

To date, Transphorm’s product portfolio consists of 600V and 650V discrete FETs spanning TO-220, TO-247, and PQFN88 packages for power levels up to 4.5 kilowatts. The TPH3212PS fills a power level gap in the company’s second generation product line, specifically between the 52mΩ and 110mΩ FETs. As a result, battery charger, PV inverter, server and servo motor manufacturers gain more design flexibility with Transphorm’s newest high-quality, high-reliability discrete device.

Release of the TPH3212PS remains in step with Transphorm’s mission to enable design engineers to effectively implement GaN technology into designs. The company develops its GaN in well-understood TO-XXX and PQFN88 packages. Further, Transphorm uses the high-reliability cascode configuration, which eliminates the need for custom drivers and—most importantly—considerably increases the GaN FET’s gate safety margin.

“Transphorm aims to enable the market by delivering GaN in the highest quality, highest reliability format as possible,” said Umesh Mishra, CTO, Transphorm. “We recognize GaN is not just a drop-in replacement for silicon MOSFETs used today. Board redesign and system modifications are required to capitalize on GaN’s complete set of benefits from performance through to system cost. If we can minimize that learning curve by working with well-known packages and a configuration that behaves similarly to a MOSFET—we believe the industry will move further faster.”

Notable TPH3212PS benefits include:

  • 30 to 40 percent increase in system level power density
  • 2x to 4x faster switching compared to silicon; lowering crossover losses to increase system efficiency
  • Compatible with off-the-shelf gate drivers; increasing gate safety margin to an industry-leading, unmatched +/- maximum 18V gate drive
  • For designs moving from standard PFC to bridgeless totem-pole: eliminates use of a bridge rectifier, parallel FETs, and additional passives as the power level increases; reducing overall system cost

Wolfspeed Delivers Industry’s First 1000V SiC MOSFET
Posted: 2016-10-6
Meets growing demand for efficient electric vehicle fast battery chargers

Wolfspeed, a Cree Company and a leader in silicon carbide (SiC) power products, has introduced a 1000V MOSFET that enables a reduction in overall system cost, while improving system efficiency and decreasing system-size. The new MOSFET, specially optimized for fast charging and industrial power supplies, enables a 30 percent reduction in component-count while achieving more than 3x increase in power density and a 33 percent increase in output power.

“Supporting the widespread implementation of off-board charging stations, Wolfspeed’s technology enables smaller, more efficient charging systems that provide higher power charging at lower overall cost. This market requires high efficiency and wide output voltage range to address the various electric vehicle battery voltages being introduced by automotive suppliers,” explained John Palmour, CTO of Wolfspeed.

“Wolfspeed’s new 1000V SiC MOSFET offers system designers ultra-fast switching speeds with a fraction of a silicon MOSFET’s switching losses. The figure-of-merit delivered by this device is beyond the reach of any competing silicon-based MOSFET,” Palmour added.

With the introduction of its 1000V SiC MOSFET, Wolfspeed leads the market with the industry’s most complete device portfolio. Wolfspeed was the first company to release a commercially qualified SiC MOSFET in 2011 and remains a leader today, committed to delivering great technology and value.

Designers can reduce component-count by moving from silicon-based, three-level topologies to simpler two-level topologies made possible by the 1000 Vds rating of the SiC MOSFET. The increase in output power in a reduced footprint is realized by the ultra-low output capacitance―as low as 60pF― which significantly lowers switching losses. This device enables operations at higher switching frequencies, which shrinks the size of the resonant tank elements and decreases overall losses, thus reducing heatsink requirements. Wolfspeed has determined these proof-points by constructing a 20kW full-bridge resonant LLC converter and comparing it to a market-leading 15kW silicon system.

CUI’s External Ac-Dc Power Supplies Now Meet EU’s CoC Tier 2 Efficiency Standards
Posted: 2016-9-22

CUI announced that the majority of its line of external ac-dc power supplies now meet the European Union’s (EU) Code of Conduct (CoC) Tier 1 and CoC Tier 2 efficiency standards.

The European Union’s CoC Tier 1 effectively harmonizes the EU with US DoE Level VI and became effective as a voluntary requirement from January 2014, two years ahead of Level VI. Its adoption as an EU Ecodesign rule is currently under review to become law with an implementation date of January 2017. The more stringent CoC Tier 2 requirement became effective on a voluntary basis from January 2016 and is similarly under review to become law as an Ecodesign rule from January 2018.

The key difference between the CoC requirements and Level VI is the new 10% load measure, which imposes efficiency requirements under a low-load condition where historically most types of power supplies have been notoriously inefficient. While CoC Tier 1 includes the new 10% load measure, its no-load and active mode limits are less stringent than DoE Level VI. CoC Tier 2 further tightens the no-load and active mode power consumption limits for key classes of power adapters enacted by Level VI and covers both standard voltage and low voltage adapters.

“This announcement is a part of CUI’s ongoing effort to stay ahead of the rapidly evolving global efficiency regulations,” stated Kraig Kawada, VP of Product Management at CUI. “Though the EU’s CoC standards are still voluntary, we want to make sure our customers’ designs are properly future-proofed in the event that these tighter efficiency rules become law.”

ON Semiconductor Expands Breadth of Options for Low-Light Industrial Imaging Applications
Posted: 2016-9-16
New 8-megapixel IT-EMCCD device, integrated cooler option for family provide new capabilities for medical, scientific & surveillance imaging

ON Semiconductor, driving energy efficient innovations, continues to strengthen its position in low-light imaging solutions for industrial markets with the introduction of new products based on interline transfer electron multiplying charge-coupled device (IT-EMCCD) technology.

The new 8-megapixel KAE-08151 image sensor is the second device to use the company's IT-EMCCD technology, delivering the same sub-electron noise floor and imaging versatility as the existing 1080p resolution KAE-02150 image sensor. With a 22 millimeter diagonal (4/3 optical format) that matches the imaging path of professional microscopes, the KAE-08151 directly targets high resolution microscopy and scientific imaging applications operating in lighting regimes that can range from sub-lux to bright-light imaging. In addition, a new packaging option is available for both devices in this family, which incorporates a thermoelectric cooler (TEC) directly into the package design. This integrated cooler simplifies development of a cooled camera that optimizes the performance available from these devices.

"The compelling combination of performance and flexibility provided by IT-EMCCD technology is providing significant benefits for low-light imaging across key industrial imaging applications," stated Herb Erhardt, Vice President and General Manager, Industrial Solutions Division, Image Sensor Group at ON Semiconductor. "By expanding our product portfolio with a new resolution node and options that simplify the integration process for camera manufacturers, end customers will be presented with even more ways to leverage the advantages of this unique technology."

IT-EMCCD devices combine two established imaging technologies with a unique output structure to enable a new class of low-noise, high-dynamic range imaging. While interline transfer CCDs combine superior image quality and uniformity with a highly efficient electronic shutter, this technology is not always ideal for very low-light imaging because of the overall noise floor of their outputs. Conversely, EMCCD image sensors excel at low-noise imaging, but historically have been available only as low resolution devices with limited dynamic range. Combining these technologies allows the low-noise architecture of EMCCD to be extended to multi-megapixel resolution image sensors for the first time, and an innovative output design allows both standard CCD (low-gain) and EMCCD (high-gain) outputs to be utilized for a single image capture - extending scene detection from sunlight to starlight in a single image.

Cornell Dubilier Hermetically Sealed Aluminum Electrolytic Capacitor Line Expands to Higher Voltages
Posted: 2016-9-16
The world’s only hermetic aluminum electrolytic capacitor line with a glass-to-metal seal, now available up to 250 Vdc

Cornell Dubilier Electronics, Inc. (CDE) has announced significantly higher voltage values for its MLSH Slimpack series of hermetically sealed aluminum electrolytic capacitors.  These unique components feature a true glass-to-metal seal that prevents dry-out of the capacitor electrolyte.  As a result, they provide extraordinarily long life (5,000 hours) to more than meet the most demanding applications for military and aerospace.  With the line expansion just announced, they are now available in nine values, from 120 µF to 3,200 µF, with ratings up to 250 Vdc.

The hermetic Slimpack is an offshoot of the well-established non-hermetic Flatpack series.  The new MLSH Slimpack can be used as a replacement for parallel and series banks of wet tantalum capacitors for both new and existing designs.  This change is especially beneficial where bulk storage is paramount.   MLSH Slimpack devices measure 1.0” x 1.5” x 0.5”, weigh less and have more capacitance than a parallel bank of three or more wet tantalum capacitors.  High rated capacitance is maintained at temperatures as low as -55 °C, a key requirement for power supplies used in military and aerospace applications.  Top-end temperature rating is 125 °C.

All devices in the MLSH Slimpack series feature rugged stainless steel cases with a vibration rating of 80g.  In most applications, there are significant cost and space savings vs. a comparably rated bank of wet tantalum capacitors.   The new high-voltage MLSH Slimpacks eliminate the need for series banking.
Since its founding in 1909, CDE has been dedicated to advancing capacitor technology for new applications. The company combines innovative products with engineering expertise to provide reliable component solutions for inverters, wind and solar power, electric vehicles, power supplies, motor drives, HVAC, motors, welding, aerospace, telecom, medical equipment and UPS systems.

Microchip and AWS collaborated to develop this integrated solution to help IoT devices quickly and easily comply with AWS IoT’s mutual authentication security model. Using Microchip’s new security solution will help companies implement these security best practices from evaluation through production. The solution adds a high level of security, simplifies the supply chain, and is now one of the fastest ways to connect to the AWS Cloud. 

Currently, third party manufacturers of devices that connect to AWS IoT service must take specific actions to comply with the advanced security model. First, they must pre-register their security authority to AWS servers in order to establish a trust model. Second, for each IoT device they must generate unique cryptographic keys that are mathematically linked to the pre-registered security authority.  Finally, the unique device keys must remain secret for the life of the device. In volume production, the generation and secure handling of these unique keys can be a daunting challenge in the chain of manufacturing especially where third parties with different trust and compliance levels are involved.

Microchip’s end-to-end security solution handles this process during three production steps. First, the AT88CKECC kit will allow customers to meet the security standard of AWS’s mutual authentication model and easily connect to the AWS IoT platform during the evaluation and engineering phase. Second, the AWS-ECC508 device assists with meeting security standards during the prototyping and pre-production phase. Finally, devices will be customized for production stages to ensure information security in customer applications.

Customers simply solder the device on the board and connect it over I2C to the host microcontroller (MCU) which runs an AWS Software Development Kit (SDK) leveraging the ECC508 device for AWS IoT. Once this is complete, there is no need to load unique keys and certificates required for authentication during the manufacturing of the device as the AWS-ECC508 is pre-configured to be recognized by AWS without any intervention. All the information is contained in a small (3x2 mm), easy to deploy crypto companion device.

AWS and the ECC508 device naturally complement each other with comprehensive mutual authentication security capabilities.  The device has strong resistance against environmental and physical tampering including countermeasures against expert intrusion attempts. In addition, the device features a high quality random number generator, the internal generation of secure unique keys and the ability to seamlessly accommodate various production flows in the most cost-effective manner.  A typical IoT device consists of a small [8-bit] microcontroller, and is battery powered.  It is typically constrained for resources like central processing unit (CPU) performance to provide low latency responsiveness, memory and code space for security protocols and for how much power they can consume in order to preserve battery life. The ECC508 device has a low-power processor-agnostic cryptographic acceleration for compatibility with the widest range of resource constrained IoT devices.

“We understand the often complex nature of implementing AWS mutual authentication in microcontrollers,” said Nuri Dagdeviren, vice president and general manager of secure products at Atmel, a wholly-owned subsidiary of Microchip. “The customer would need to have some understanding of how to secure a software implementation, and this often creates a huge barrier. We have had a long standing relationship with AWS and are thrilled to have the opportunity to work with the world’s largest cloud provider to build a solution that helps our customers easily and securely connect to the AWS Cloud.”

“We have a strong relationship with Microchip and we are very excited to be able to offer a world-class solution to anyone who wishes to deploy secure and scalable IoT solutions on our cloud services,” said Marco Argenti, vice president, Mobile and IoT, Amazon Web Services, Inc. “For all companies we work with, embracing security best practices are an essential step in achieving our mutual goal of offering customers the best and most secure IoT platform available. We believe this new solution will be one of the simplest and most cost-effective ways for our customers to comply with our security best practices.”

ON Semiconductor Introduces Automotive Power Integrated Module Solution for Next Generation Automotive BLDC Systems
Posted: 2016-7-16
Highly integrated module featuring 30 A, 40 V MOSFETs enables development of more compact, streamlined motor drives exhibiting elevated degrees of reliability

ON Semiconductor (Nasdaq: ON), driving energy efficiency innovations, has further expanded its portfolio of automotive Power Integrated Modules (PIMs) with the introduction of the STK984-190-E. Optimized for driving 3-phase brushless DC motors in modern automotive applications, this module contains six 40 V, 30 A MOSFETs configured as a three-phase bridge with an additional 40 V, 30 A high-side reverse battery protection MOSFET. The MOSFETs are mounted onto a direct bonded copper (DBC) substrate, resulting in a compact module with excellent thermal performance taking up only half of the board space used by an equivalent discrete solution.

The module is suitable for use in 12 V automotive electric motor drive applications with power ratings up to 300 W, such as electric pumps, fans and windscreen wipers. Used in combination with motor controllers, such as LV8907UW, designers can build high efficiency BLDC solution with best-in-class thermal performance, built-in diagnostics, and an ultra-small PCB that saves critical size and weight.

Using the module allows both the component count and the bill of materials costs to be reduced substantially. The DBC substrate reduces the thermal resistance, which reduces the operating temperature of the MOSFETs. This reduces power losses and increases reliability due to a reduced change in temperature during thermal cycling. Reliability is also improved by the isolation provided by the DBC substrate. STK984-190-E has a specified operational temperature range of -40°C to 150°C. The integrated MOSFETs are all AEC-Q101 qualified.

"At least 13-15 discrete components would typically be needed to develop an effective BLDC drive solution, whereas the STK984-190-E automotive power module needs less than half that," states Chris Chey, General Manager of System Solutions Group at ON Semiconductor. "In addition to its compact size, the strong thermal performance of the STK984-190-E allows a smaller heatsink to be employed. The marked reduction in system size and weight that it enables, mean the current challenges that engineers face in terms of boosting fuel economy and overcoming space constraints can be fully addressed."

New Technology Report Introduced at APEC 2015
Posted: 2015-3-21
Current Development in 3D Packaging With Focus on Embedded Substrate Technologies

At APEC 2015, the PSMA Packaging Committee will introduce the first comprehensive study of the feasibility of using Embedded Substrate Technologies to build power sources. The report entitled “Current Developments in 3D Packaging with Focus on Embedded Substrate Technologies” will also be discussed at the Industry Session on 3D Packaging. The report was prepared under contract by LTEC Corporation with work subcontracted to Anagenesis and Fraunhofer-Institute. The intent of this article is to provide PSMA members a high level preview of the contents of Technical Report.

The PSMA Packaging Committee believes the 340 page report with extensive illustrations of the leading edge product technologies will provide valuable insights to executives and managers in their own analysis of how currently available materials and processes could be best used for the creation of advanced high efficiency, high power-density power electronic products. The report builds upon the findings of the Phase I report - 3D Power Packaging - issued by the Power Sources Manufacturers Association (PSMA) Packaging Committee in 2014.


Let’s begin with a little background. The power electronics industry and the semiconductor industry are inseparably intertwined with one another, and both are facing unprecedented market challenges for efficiency, cost, construction and thermal issues which provide many opportunities for innovation. These industries are in the focal point of the “energy challenge” a multifaceted problem that involves mobile and cloud infrastructure systems, Internet-of-Things, renewable energy, smart grid, vehicle electrification, and across-the-board power efficiency enhancements in order to keep up with the industry's rapid growth in data consumption. These are the competiveness and sustainability challenges of the twenty-first century.

The paradigm shift we have been experiencing in semiconductor packaging technology was brought about by advanced deep submicron semiconductor technology reaching a “cost barrier” that prevented further cost reduction by adding more functions to the semiconductor die. This barrier was circumvented through the development of wafer thinning that enabled through-silicon-via (TSV) technology, and the eventual introduction of 2.5D and 3D integration that facilitated heterogeneous (“More than Moore”) integration. It will allow the power requirements of the digital load to increase 2 to 5 times, within the same footprint, in a single generation. The power sources community must now find ways to package power sources that will meet this demand, but with no increase in footprint.

In parallel, power semiconductor technology has been facing a “construction barrier” that prevents realization of the huge benefits new technology can offer in terms of increased power efficiency and higher power density. These new technologies which include gallium-nitrogen (GaN), silicon-carbon (SiC), and gallium-arsenic (GaAs) power semiconductor devices all require operation in an environment that is free of bond wires and minimizes parasitic interconnect elements. The best possible packaging technology to achieve this is embedding active and passive components in organic or inorganic substrates.

Overview of the Report

The report begins with a discussion of PCB embedding technology, which is fueled by the rapid evolution of low-power embedding and 3D packaging technologies, which are in high volume production. These technologies will in turn enable power electronic systems to deliver higher efficiency and higher power density.

In addition to substrates the report dedicates entire chapters to each of the passive components (resistors, capacitor, and inductors) as well interposers and additive manufacturing.

The report also discusses high temperature die and component attach technologies that are evolving rapidly in the research labs; however, a single, low-cost, “one-size-fits-all applications” high-lead solder-substitution technology is currently unavailable and addresses the fact that high power-density component embedding and 3D packaging of power semiconductor devices also have to overcome a “thermal barrier.” Simply stated, it is more challenging to remove heat generated within the body of a 3D integrated system than from a planar, two-dimensional surface. This leads to a discussion of advanced thermal management technologies which are key enablers for 3D packaging as well as PCB embedding.

The authors acknowledge and devote a chapter to the fact that high power-density component embedding and 3D packaging of power semiconductor devices also have to overcome a “thermal barrier.” Simply stated, it is more challenging to remove heat generated within the body of a 3D integrated system than from a planar, two-dimensional surface. This leads to a discussion of advanced thermal management technologies which are key enablers for 3D packaging as well as PCB embedding.

In addition to their primary research, the team conducted a worldwide literature review and analysis of research and development (R&D) published by participating organizations in the USA, Asia-Pacific Region, and the EU, and identified several potentially high-impact technologies of interest to the power electronics and the semiconductor industries.. In terms of leadership positions, Germany and the EU appear to lead in the area of high-power PCB embedding and research into vertical interconnect/high-lead replacement technology, while Japan is leading in low power, high-density embedding, high performance, low CTE, high modulus (low warpage) substrates, and organic interposer technologies.

Finally the report highlights some of the technology gaps as well as a recognition that this new technology requires updated or additional standards for manufacturing and testing. This report reviews the existing and pending new standards for PCB embedding which the IPC Association has taken the lead to author. However, much additional standard action is needed since the manufacturing supply chain is still evolving. Procedures need to evolve to establish compatibility of up-top metal-die design and PCB layout rules, testing, quality control, and for assigning ownership of failure.

In summary, there has been substantial progress and excellent opportunities lie ahead for the power electronics and semiconductor industries and the entire manufacturing ecosystem to embrace PCB embedding and 3D packaging technologies for power electronic applications. The intersection of these technologies with the emerging wide-bandgap power semiconductor technology creates truly exciting possibilities at the same time the power electronics industry faces unprecedented challenges to help mitigate the fast growing demand for electricity and environmental problems our world faces. Embedded substrate packaging technologies can be, and will be deployed in hybrid and electric vehicles, alternative energy generation and distribution systems, smart grid, industrial, and military aerospace applications in the coming years and beyond. These technologies, combined with wide-bandgap semiconductor devices will literally re-vitalize the entire power electronic infrastructure block by block, module by module, for the twenty-first century.

PSMA Publishes Technology Report: “Current Development in 3D Packaging With Focus on Embedded Substrate Technologies”
Posted: 2015-3-17
Comprehensive report is the first to address “More than Moore” digital power demands by accelerating the development of higher density power sources using new, disruptive packaging technologies

March 16, 2015—The PSMA (Power Sources Manufacturers Association) Packaging Committee announced today that it has published a report titled “Current Developments in 3D Packaging With Focus on Embedded Substrate Technologies.” The first comprehensive study on using embedded substrate technology for building power sources, the report contains extensive research and product illustrations geared to an audience of technology executives and design engineers. Its purpose is to offer an in-depth industry perspective on how currently available materials and processes can be best used for the creation of advanced high-efficiency, high-power-density power products.

The PSMA created the 3D packaging report to address the pressing demands in the power industry to accelerate the development of higher density power sources. The first challenge arose from digital semiconductor packaging technology hitting a “cost barrier” brought about when advanced deep-submicron semiconductor technology could no longer reduce cost with the addition of more functions to the semiconductor die. This barrier was circumvented through the development of wafer thinning that enabled through-silicon-via (TSV) technology and the eventual introduction of 2.5D and 3D integration, which facilitated heterogeneous (“More than Moore”) integration. This integration allowed the power requirements of the digital load to increase two to five times, within the same footprint, in a single generation. Now the power industry is tasked with finding ways news ways to package power sources that will meet this demand, but without increasing footprint.

In parallel, power semiconductor technology is facing a “construction barrier” that prevents the realization of the significant benefits new technology can offer in terms of increased power efficiency and higher power density.  These new technologies, including gallium-nitride (GaN), silicon-carbide (SiC), and gallium-arsenic (GaAs) power semiconductor devices, all require operation in a package that is free of bond wires and that minimizes parasitic interconnect elements. Both of these challenges can be addressed with power packaging utilizing embedded substrate technologies and are addressed in the report.

The PSMA’s 340-page report, prepared under contract by LTEC Corporation with work subcontracted to Anagenesis and Fraunhofer-Institute, is based on the Packaging Committee’s extensive research of over 750 articles and papers, analysis of 450 presentations/papers, and by conducting 30 industry expert interviews. Information was also derived from attendance at 10 industry conferences, workshops and seminars. The report contains 172 links and 394 citations.
The report provides detailed analysis of substrates (organic and inorganic), components (actives and passives), thermal management, high temperature die, packaging technologies, interposers, as well as additive manufacturing and laser fabrication. Each passive component (resistors, capacitors, inductors) has an entire chapter detailing which suppliers are currently shipping products usable in power sources.  Every chapter covers manufacturing issues and includes references to contract manufacturing companies already producing power products utilizing embedded substrate technology. Embedded substrate packaging leverages the large investment made by the digital industry in advanced packaging technologies and is being used to resolve the power source construction challenge. As the report demonstrates, 3D power packaging using embedded substrate technology is a disruptive technology, in that it enables large increases in power density and efficiency.

Co-chairs of the PSMA Packaging Committee, Ernie Parker of Crane Aerospace & Electronics and Brian Narveson of Narveson Consulting, described the report as “the first comprehensive document to discuss the  challenges companies will face to implement embedded substrate 3D power packaging to create the significantly higher power densities driven by the “More than Moore” digital power demands.”

The PSMA report on 3D packaging will be provided free of charge to PSMA Regular and Associate members.  Affiliate members can purchase the report for the reduced price of $190.  Others interested in the report may order a copy from PSMA for $2,990.
