The PSI5 interface supports the latest requirements of chassis-position detection sensors. **

HAC 39xy sensors enable angular measurements up to 360° with ferrite 2-pole magnets and linear measurements up to 35 mm by using two-pole bar magnets. The stray-field robust position detection can take both measurement types, with additional 3D measurements resulting in two independent angles. The SENT interface transmits data from both angles while the sensors achieve a high ESD immunity and meet all of the stringent EMC requirements. Samples are available now; mass production will start by the end of 2021.

The patented 3D HAL pixel-cell technology is the core of the HAC 39xy sensors, and accurately measures magnetic fields while being insensitive to stray fields. The unique concept of the masterHAL® sensor line is based on an array of Hall plates. The highly flexible sensor array helps design engineers select the best operation mode for any given measurement task.

With its flexible architecture, HAC 39xy offers a wide range of configuration possibilities. It features a powerful DSP, which is responsible for fast signal processing, and an embedded microcontroller that performs the interface configuration and supervision of the Functional Safety related tasks. The innovative architecture of the HAC 39xy sensors makes it easy for customers to develop new solutions using fast prototyping techniques. It also enables quick and easy adaptation to changes in interface standards such as SENT and PSI5.

The pins of the TO92UF package can be welded or soldered directly to a lead frame, eliminating the need for a printed circuit board (PCB), thus reducing the total system size and cost. Furthermore, the overall system long-term reliability is significantly improved.

The InnoSwitch4-CZ was a natural choice for Anker's new Nano II series of USB-C chargers. Its outstanding levels of integration and efficiency are key to the Nano II series’ extremely compact design.”

The InnoSwitch4-CZ family incorporates 750 V switch, primary and secondary controllers, ClampZero interface, synchronous rectification, and safety-rated feedback in a single, compact InSOP-24D package. A steady state switching frequency of up to 140 kHz minimizes transformer size, further increasing power density.  In contrast with older active clamp flyback approaches, the InnoSwitch4-CZ and ClampZero combination provides up to 95% efficiency and maintains very high efficiency across variations in line voltage, system load and output voltage. This is achieved with variable frequency asymmetrical control of the active clamp with intelligent zero-voltage switching, enabling both discontinuous and continuous conduction modes of operation, greatly enhancing design flexibility and maximizing efficiency across the entire operating envelope. The new flyback switcher ICs enable exceptional CV/CC accuracy, independent of external components, and consume less than 30 mW no-load including line-sensing safety and protection features.

 

Targeting high efficiency compact USB PD adapters, high-density flyback designs up to 110 W and high-efficiency CV/CC power supplies, InnoSwitch4-CZ ICs provide variable output voltage and constant current profiles. Devices are fully protected featuring auto-restart or latching fault response for output over-voltage and under-voltage protection, multiple output under-voltage fault thresholds and latching or hysteretic primary over-temperature protection.

A 5mA input current draw is typical under zero load conditions and can be reduced to typically 0.25mA when the module is in standby mode using the output inhibit function.  The low quiescent current allows battery powered equipment to remain functional longer during periods of non-operation.

The basic feature models include an output voltage adjustment pin, positive or negative logic remote on-off, positive remote sense, plus input under-voltage, over-current and thermal protection.  The full-featured models are equipped with a power good signal, output current monitoring and the ability to synchronize the operating frequency to minimize system noise. 

All the i7C2W converters measure 34mm x 36.8mm with a height of 14.7mm and follow the industry standard 1/16th brick pin-out.  The i7C design reduces the number of external       components, saving both cost and board space.

All models are certified to IEC/UL/CSA/EN 62368-1 and carry the CE mark for the Low Voltage and RoHS Directives.

More information on the 20A i7C2W models, including distributor inventory and evaluation boards, can be obtained from the TDK-Lambda Americas website at https://www.us.lambda.tdk.com.

Small form factor PoL regulator offers high efficiency and excellent thermal performance
Posted: 2021-3-25

Flex Power Modules announces the PNA series, an analog non-isolated point of load (PoL) regulator that offers excellent efficiency and thermal performance in a small form factor. Its compact size and wide input voltage range of 9 V to 36 V mean that it is ideal for a range of industrial applications, including robotics, factory automation and process control, and that it is suitable for both 12 V and 24 V power systems.

The regulator has high efficiency of 95.5% at 12 Vin and 5.5 Vout, at full load. This reduces power losses and heat dissipation. It delivers an adjustable output of 0.9 V to 5.5 V, at up to 6 A output current, which translates to a maximum power output of 33 W.

The PNA series provides good thermal performance, and can operate at full load in ambient temperatures above 100°C. It has an operating temperature range of -40 °C to + 125 °C.

To save board space, the PNA series is provided in a small form factor, measuring 13 x 12.35 x 6.2 mm (0.51 x 0.48 x 0.24 in). This supports bottom-side PCB mounting, thus further reducing space requirements.

The regulator is available at a competitive cost, and provides an attractive price/performance ratio. It offers a mean time between failures (MTBF) of up to 71.84 million hours.

A voltage tracking function enables one regulator to use the output voltage of another as a reference to follow its turn-on and turn-off behavior. This simplifies the design required to make each device power-up in the correct sequence. The regulator also includes a power good (PG) function, for further control of sequencing, and supports soft start with time-based sequencing.

The PNA series can be synchronized to an external clock, which means that it eliminates beat frequencies reflected back to the input supply rail.

The first device in the series, the PNA2405S3S, will be available in Q2/2021. Samples are available now. Customers can obtain further information by contacting pm.info@flex.com.

Microchip Releases the First IEEE 802.3bt Power over Ethernet to USB Type-C® Power and Data Adapter
Posted: 2021-3-11
Enables extended installation reach of USB Type-C devices while supporting a variety of input PoE standards up to 90W and output power up to 60W

There are many consumer, enterprise and industrial devices today that have a USB Type-C port as the only input power option. While USB-C® technology can offer high power and high data rate, it limits the range of the installation to a maximum of three meters from an AC outlet. As Power over Ethernet (PoE) becomes more prevalent and a more convenient solution to provide power over a standard Ethernet cable, it is the most practical solution to provide both power and data up to 100 meters. While most adapters on the market provide only power, they provide only limited power up to 25W. Microchip Technology Inc. (Nasdaq: MCHP) today announced a PoE to USB-C adapter with the highest power capability that converts both power and data while offering up to 60W USB output power via an Ethernet cable supported by PoE infrastructure.

The adapter (part number PD-USB-DP60) can accept up to 90W of PoE and convert it to 60W output over USB-C that will power most cameras, laptops, tablets and other devices using USB-C for input power. This adapter simplifies installation by reducing dependency on AC infrastructure. Without the dependency of an AC outlet, there is no longer a range limitation of three meters and power can be delivered over 100 meters. This adapter also enhances the remote power management capabilities of the USB-C power device. The remote power reset capability, provided by the PoE source, allows power cycling via web interface or Simple Network Management Protocol (SNMP) to reset the device, rather than having to manually unplug and restart at the location of the equipment.

Microchip’s PoE to USB-C adapter can connect to a variety of PoE sources with various standards deployed. It supports newer IEEE 802.3af/at/bt standards as well as legacy PoE standards. Having a versatile adapter is crucial due to the many different implementations of PoE already installed.

“This new device is ideal for easily deploying USB-C devices and providing them long-range power and data connectivity,” said Iris Shuker, director of Microchip's PoE business unit. “The adapters are built using Microchip’s USB power delivery ICs and PoE chipsets and are a perfect pairing with our latest PoE injectors and midspans.”

Having the capability of converting 90W input to 60W output enables devices requiring higher power charging to make use of PoE that could not have done so before. The adapter can be paired with Microchip’s cost-effective single-port and multi-port (up to 24) PoE injectors/midspans and switches that comply with IEEE 802.3af/at/bt industry standards and provide up to 90W power per port. If a lower power is needed to power the USB-C device, IEEE802.3af (15.4W) or IEEE802.3at (30W) PoE sources can be used.

Microchip also offers key integratFed circuit solutions that enable the PoE to USB-C adapter, including the PD70xxx family of PoE ICs and the LAN7800 USB-to-Ethernet bridge. Functionality is enabled by Microchip’s Power Delivery Software Framework (PSF), an open-source Power Delivery (PD) stack that runs on the UPD301C PD controller and provides full PD 3.0 capability and customization for Microchip’s PD controllers, microcontrollers and USB hubs.

PSMA Publishes Technology Report: 3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies
Posted: 2018-9-6
Comprehensive report is the first to address higher power embeddable passives that will accelerate the development of higher density power sources using new, 3D disruptive packaging technologies

The Power Sources Manufacturers Association (PSMA) Packaging Committee announces the publication of its latest report titled, “3D Power Packaging with Focus on Embedded Passive Component and Substrate Technologies.” This is the third in a series of reports focused on using embedded substrate technology for building power sources. It is the first extensive study of embeddable passive components both available and in development for use in the power path of power sources. The report contains extensive research and product illustrations geared to an audience of technology executives and design engineers.

Miniaturization of passive components without compromising their power handling and efficiency and their integration with actives has always been a key focus for power packaging. There is also an increasing trend to vertical or 3D package integration to address the performance issues by eliminating parasitics from interconnections. Embedding gives lowest package inductance and enables co-integration of power systems and drivers in a single package with direct interconnection between gate driver circuits and switches with shortest interconnection length. This has become even more important with the rapid emergence of wide bandgap power switching devices. This, however, leads to several process integration and reliability challenges that need to be systematically addressed.

Georgia Tech Packaging Research Center, under contract from PSMA systematically surveyed the recent advances in passives, active embedding and 3D passive-active integration to generate this report, with emphasis on 3D power packaging enabled by advances in passive components and embedding of actives in power packages. A detailed literature study was conducted on key advances in embedded passive technologies and related topics. Emerging nanomaterials, processes and technologies are described in detail for inductors, capacitors and resistors. Nanostructured materials provide additional degrees of freedoms in enhancing the properties to improve the performance metrics such as volumetric density and efficiency of the components. Key enabling building-blocks are described for each technology. The manufacturing challenges are also highlighted in advancing the components to improve performance. Industry leaders were surveyed to get the recent technology advances in each category. Roadmaps are projected for passive component advances and active embedding technologies.

The trends and roadmaps in 3D power packaging are also described in three categories: low power (1-100 W), medium power (100-1000 W) and high power (10-100 kW). Integration in each category is classified into lead-frame-based, substrate-embedding based and traditional ceramic substrates. Active embedding with panel-scale substrate manufacturing is also reviewed in detail. Recent innovations in substrate materials and associated reliability challenges such as via cracking, dielectric cracking or electric breakdown are highlighted. Advances in die-attach solutions with sintered nanocopper are reviewed, highlighting the evolution of low-stress sintered copper-based die-attach solutions.

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 passives in 3D power packaging to create the significantly higher power densities.

The PSMA report on 3D packaging was provided free of charge to PSMA Regular and Associate Company members.  Additional copies may be purchased at the member price of $290. PSMA Affiliate members may also purchase the report for $290. The report is available to non-members for purchase on the PSMA website (www.psma.com/publications) for the price of $3,490.
