Emerging Mixed-Signal Control and Hybrid Topological Solutions for Designing High Power Density Dc-Dc SMPS February 22
Abstract: In numerous cost and volume sensitive applications reactive components (inductors and capacitors) of switch-mode power supplies (SMPS) have become main contributors to the overall size, cost, and weight of electronic devices. Furthermore, conflicting requirements for size reduction of the SMPS and increase in their power delivery requirements have pushed conventional dc-dc SMPS solution close to (or beyond) their limitations.
This seminar will address those limitations and present several emerging practical control and topological solutions that, potentially, provide drastic reduction of the size of SMPS and power processing efficiency improvements at the same time.
Practical on-chip implementation of fast transient control methods, based on minimum voltage deviation, will be presented.
On the topological side, classes of reduced voltage swing converters, which are based on hybrid capacitive and inductive energy processing, will be reviewed and several new topological solutions presented.

Worth of a Watt – Its Capital Equivalent April 12
Abstract: In a study presented at the INTELEC conference in 1978 and updated in 1981, the capital equivalent of the cost of dissipating a watt in a Bell System central office was examined. It was determined that the worth of an ac watt in 1977 was $7.22, and in 1979, with then-current data, $11.31. About 40 years have passed since these studies. This talk examines the economic and technology changes that have developed since that time, and presents a revised estimate of the worth of a watt as it is processed through a typical central office power chain. The technology of the load in a central office is also reviewed to provide a sense of the changing level of dissipation that can be expected. The structure of the analysis can be applied in other environments such as web servers.
The growing awareness of sustainable technologies reminds us that an ordinary incandescent light bulb, such as a 100 W bulb, initially costs about $1.50 and generates about $15 of electrical expense over its 1500 hour lifetime. It is widely recognized that LED bulbs, even though they initially cost more, are unarguably more economical because of their higher luminous efficiency. Following a similar thought process, this talk reviews the present economics of electric energy in telecommunications and other business environments so that reasonable trade-offs between higher first costs and better power conversion efficiencies of power processing equipment can be made.

Getting from 48 Volts in Emerging Server and Automotive Applications June 28
Abstract: Cloud servers, advanced gaming systems, artificial intelligence, cryptocurrency mining, and automotive electronics are all converging rapidly on 48 Volts as the new standard bus voltage. 48 V has the advantage of not requiring isolation and is therefore simpler, smaller, more efficient, and lower cost than other power conversion architectures. In every case, the relatively new GaN transistors and integrated circuits have demonstrated the ability to convert to-and-from 48 Volts with higher efficiency, and smaller size.

Monolithic GaN Device Integration Drives Efficiency, Density and Reliability in Power Conversion August 16, 2018
Abstract:
Forty years ago, the industry experienced a first revolution in power electronics. The silicon (Si) bipolar-junction transistor was surpassed in on-state and switching performance by the development of commercial power MOSFETs such as International Rectifier’s ‘HEXFET’. With the new, ‘fast’ powertrain components came advances in magnetic materials. New, kHz-switching regulator topologies or ‘switched-mode power supplies’ (SMPS) challenged the dominance of traditional 50 Hz linear regulators, offering the promise of higher efficiencies, higher densities and even lower cost. Device integration, in the form of analog application-specific ICs (ASICs) developed by Silicon General, Unitrode & others, was the catalyst to enable simple, cost-effective and industry-proven designs.
In the following decade, the power supply industry experienced a 5x increase in power density, a 5x reduction in losses in energy savings and a 3x reduction in costs. The next 30 years saw incremental improvements but no performance shifts as dramatic as the first revolution.
Today, we are at the start of the second revolution. Gallium Nitride (GaN) powertrains replace Si switches, MHz-switching magnetic materials are broadly available and new, soft-switching topologies such as Active Clamp Flyback (ACF) and critical conduction mode (CrCM) totem-pole PFC are available. Forty years later, device integration is again the catalyst to sparking the performance, size and cost revolution.
Early discrete GaN implementations need complex, expensive control and protection circuits, which restrict device performance and so limit application advances and market adoption. Now, the monolithic, lateral integration of FET, drive and logic - all in GaN – creates easy-to-use, high-speed, “digital-in, power-out” GaNFast™ Power ICs to drive speed and efficiency increases in power conversion. Designers can now achieve 3x power density increases at similar or lower BOM costs vs. typical old and slow Si systems.
The seminar will introduce the 650 V eMode GaN power IC structure, with a step-by-step review including device- and circuit-related reliability structures / techniques. System benefits will be described using a wide range of converters from 27W to 3.2kW and 300 kHz to 1MHz+.

Emerging Embedded Passive Technologies that Enable High Density 3D Power Packaging October 4, 2018
Abstract:
This presentation will review: a) passive component performance, design and geometry targets for power delivery in emerging high-performance and mobile computing; b) review the state-of-the-art and leading-edge research in component materials, fabrication and integration to realize 3D power packaging.
Power conversion close to the load (ex. processor), with high power conversion ratio from the high-voltage bus to the point-of-load, and low losses are the key requirements for efficient power conversion. Component designs depend on the power requirements and converter topology utilized for different applications such as high-performance computing (AI, servers, data center) and mobile computing. In the fully-integrated voltage regulator topology, several small inductors are used in a multi-phase switching architecture. On the other hand, traditional point-of-load converters deliver extremely high current and are very sensitive to coil DC resistance. For high-performance computing, component integration and designs are also driven by the package architectures such as silicon interposers (chip on wafer on substrate or CoWoS), fan-out packaging, laminate embedding or recent approaches from Intel such as EMIB (embedded multi die interconnect bridge). The first part of the project will analyze different scenarios for voltage regulator applications and will project the needs, current-handling, DC resistance targets for various on-chip and package-embedded components.
The next part of the presentation will review on-chip, IPD and package-integrated inductor implementations with thin nanomagnetic films and package-integrated polymer composite inductor films. These are explored for switching regulator topologies with high current bias and low ripple voltages. Thin nanomagnetic films are deposited through sputtering techniques to achieve precise nanostructures for high permeability and low coercivity. Recent advances have shown that these films can be used in inductors for high current handling while managing the L/R ratio. The low currents in the inductors make them more forgiving to DC resistance, allowing their integration with thin BEOL (back end of the line) design rules. However, polymer composite inductors are still preferred for laminate-integrated inductors because they can be designed with lower DC losses, and handle higher currents with thicker films that utilize package design rules, and at much lower cost. They also can have isotropic properties for more flexibility in inductor design. For isolated power conversion, switching losses dominate the loss budget. Low-loss ferrites and nanocrystalline or amorphous ribbons are utilized for these applications, benefiting from their low-frequency (<5 MHz) power conversion. Recent advances and their potential to address the component needs will be the key focus of the final part of the presentation.
Magnetics do not scale with the rest of the package. They also add EMI and other limitations. This led to more interest in capacitor-based power conversion. The need for temperature-stability, high-voltage stability, ultra-low ESR (< 5 milliohms x microfarad) have led to the development of high-permittivity but paraelectric capacitors or antiferroelectric capacitors. For higher densities, ultra-thin MLCCs are being developed with densities of 2 microfarad/mm2 in ~200 micron components. These components are also embedded into the package and interconnected with plated copper on copper terminals. Component thickness, need for pick-and-place and thermal instabilities still impose limitations with these technologies, leading way to planar embedded film capacitors based on high surface area tantalum or Aluminum film capacitors. The third part of the presentation focuses on advanced capacitor technologies for passive embedding.
The talk will conclude with the roadmaps for high-power and low-power magnetics and capacitors.

Power Connections for Higher Loads and Hotter Environments October 18, 2018
Abstract:
As power demands continue to increase and allowable space shrinks, power density and ambient temperatures get higher and higher. This combined with the need to reduce energy losses complicates power connector selection. In some applications, system designers are hitting the limits of their architecture and are looking for ways to get just a little more power through. As a result, the power systems, including connectors, require more consideration earlier in the design process.
This presentation will cover some power connector design fundamentals including new surface finish technologies entering the market that reduce resistance to enable higher currents. Limiters to higher voltage applications are reviewed, as well as how to select and test connectors for higher temperature applications. Finally, current rating testing is scrutinized to determine how relevant it is to a customer’s application; alternate ways are presented to compare connectors from multiple vendors.

Delivering the Inner Power of SoCs: The Value of Fully Integrated Voltage Regulators in SoCs November 15, 2018
Abstract: As SoCs and processors migrate to smaller and smaller deep-submicron nodes, several new power management challenges are emerging. The number of independent voltage rails on chip has increased from a few to a range of 20 to 50, significantly driving up the cost and area of power management solutions, not to mention the complexity of both PCB and package routing from the external voltage regulators to the voltage islands on the SoC. This complex routing combined with the tremendous increase in current transient speed and step size, has forced SoC designers to expand the voltage margin buffer on chip significantly, leading to a large increase in wasted power and heat. Existing power management solutions, like advanced PMIC products, are unable to effectively regulate the on-SoC voltages during transients due to the large impedance between the regulator bulk caps and the SoC die. Increasing switching frequency and bandwidth of the PMIC offers quickly diminishing returns while reducing regulator efficiency considerably.
This presentation will evaluate the emerging power management issues of SoCs and processors and how they are solved with the full integration of high-bandwidth voltage regulators (IVR) directly into the digital IC.

Powering IoT edge devices – ecosystem and use cases November 29, 2018
Abstract:
As power demands continue to increase and allowable space shrinks, power density and ambient temperatures get higher and higher. This combined with the need to reduce energy losses complicates power connector selection. In some applications, system designers are hitting the limits of their architecture and are looking for ways to get just a little more power through. As a result, the power systems, including connectors, require more consideration earlier in the design process.
This presentation will cover some power connector design fundamentals including new surface finish technologies entering the market that reduce resistance to enable higher currents. Limiters to higher voltage applications are reviewed, as well as how to select and test connectors for higher temperature applications. Finally, current rating testing is scrutinized to determine how relevant it is to a customer’s application; alternate ways are presented to compare connectors from multiple vendors.The world expects to have 1 trillion IoT sensors in place by 2025, most of them wireless edge devices. Extending battery life of these parts to reasonable service interval and ideally beyond application lifetime use is probably the biggest impediment to this becoming a reality.
The first half the webinar gives an overview of PSMA’s initiatives (driven by the Energy Harvesting Committee) to accelerate the development of a ‘power IoT’ ecosystem to address this issue. This is done through efficient power management solutions at sub mW levels as well as using energy harvesting technologies (generation and storage) where possible. This requires not just technology development but also for stakeholders to work more closely together and take a cross-disciplinary system integration approach to ensure optimised and inter-operable material and devices are developed and integrated. Many industry efforts have been taken to drive awareness and tangible momentum with key supply chain and application partners. The most recent example and culmination of these efforts are the recent APEC Industry Sessions and the EnerHarv 2018 Workshop (www.EnerHarv.com) that has given birth to the energy harvesting ecosystem.
The second half of the webinar outlines 2 high impact cases identified in an EU Industry 4.0 project COMPOSITION (www.compostion-project.eu) showing where IoT edge devices can be retrofitted in or near equipment and infrastructure in a Boston Scientific medical device factory to improve energy and resource efficiency
- sensors for tracking high value assets (high value component reels, test fixtures, measurement and inspection equipment)
- condition monitoring of reflow oven fans for predictive maintenance by detecting fan wear out (using acoustic and power sensors)
To date the work has focused determining the appropriate types of sensors and wireless infrastructure on selecting commercially available and emerging platforms. The next stage involves determining to what extent IoT device power consumption can be reduced (based on hardware platform selection, sensor data granularity & duty cycle and data gathering infrastructure) to extend battery life and also if ambient energies are available potentially for device self-powering.

Advances in Low Profile Capacitor Technology December 20, 2018
Abstract: In recent years, capacitors have become more of a focus in the electronics world. The industry is moving from a world of stable supply and relatively stable technologies, to a new order where supply of some components has become scarce, but new technologies are emerging.
Under the massive influence of consumer product development, with a focus on miniaturization, many of the MLCC manufacturers are terminating larger MLCC footprints starting from the 0603 size and larger. The electronic world, however, isn't only a consumer business. Industrial customers have significantly different requirements. High voltages, larger and more stable capacitances values, less DC bias behavior, higher mechanical stability, and much more, are in demand. With the changing availability of MLCC portfolios, how will the Industrial Market adjust to this change in the capacitor landscape? What alternatives and new technologies are available?
The PSMA Capacitor Committee’s Roadmap Webinar will share new technologies and future developments that the audience should keep an eye on. Major players, including CDE, KEMET and Wurth Electronics, will present. And they will be joined by a newcomer, Polycharge, who will discuss a brand new technology.
The participants will discuss existing alternatives and a roadmap for the mid- and long-term to help overcome the MLCC crisis. And the webinar will conclude with an outlook on an exciting new technology.
