Gallium nitride (GaN) power devices have been in volume production since March 2010 and have established a remarkable field-reliability record. An automotive application using GaN power devices in high volume is lidar (light detection and ranging) for autonomous vehicles. Lidar technology provides information about a vehicle’s surroundings, thus requiring high accuracy and reliability to ensure safety and performance. This article will discuss a novel testing mechanism developed by Efficient Power Conversion (EPC) to test eGaN devices beyond the qualification requirements of the Automotive Electronics Council (AEC) for the specific use case of lidar.

Just like life’s reality, when the aged leaves the center stage for the younger ones, Silicon is taking the bow. The advent and adoption of Gallium Nitride (GaN) have succeeded in gradually easing out the old reliable Silicon. For over four decades, power management efficiency and cost have improved steadily as innovations in power MOSFET structures, technology, and circuit topologies have kept pace with the growing need for electrical power. In the new millennium, however, the rate of improvement has slowed dramatically as the silicon power MOSFET approaches its theoretical bounds. At the same time, the new material, GaN is steadily progressing on its journey toward a theoretical performance boundary that is 6,000 times better than the aging silicon MOSFET and 300 times better than the best GaN products on the market today.

The combination of Microchip Technology’s digital signal controllers with ultra-efficient eGaN^® FETs from EPC (Efficient Power Conversion) enable best-in-class power density of 730 W/in³ for high efficiency, low cost DC-DC Conversion.

EL SEGUNDO, Calif.— July, 2020 — EPC announces the availability of the EPC9143, a 300 W DC-DC voltage regulator in 16^th brick size. The EPC9143 power module integrates Microchip’s dsPIC33CK digital signal controller (DSC) with the latest generation EPC2053 eGaN FETs from EPC to achieve 96% efficiency in a 48 V input to 12 V output conversion at 25 A.  The switching frequency of 500 kHz enables the 300 W in the very small 16^th brick format which is just 33 mm x 22.9 mm (1.3 x 0.9 in). Additional phases can be added to this scalable 2-phase design to further increase power. The flexibility of the Microchip digital controllers allows the input voltage to be adjusted from 8 V – 72 V and the output voltage from 3.3 V – 25 V.

In this second part of EEWorld’s “virtual roundtable” discussion on Class D audio, our panelists delve into the impact that the emergence of gallium-nitride (GaN) is having on Class D designs: Where are silicon devices still dominant? What are the performance benefits of using GaN in Class D amplifiers? And what are the anticipated future trends of GaN versus Silicon in Class D amplifiers? Joining us for this virtual roundtable are Joshua LeMaire (JL), Audio Systems Architect at Analog Devices; Steve Colino (SC), Vice President Strategic Technical Sales with Efficient Power Conversion; and Jens Tybo Jensen (JTJ), Head of Application Engineering for Class D Audio at Infineon Technologies.

Efficient Power Conversion (EPC) will showcase the company’s latest ePower™ Stage IC family of products showing how GaN technology’s superior performance is transforming power delivery for computing, communications, robotics, and transportation at the PCIM Europe 2020 Digital Days.

EL SEGUNDO, Calif.— June 2020 — The EPC team will be delivering three technical presentations and participating in two panel discussions on gallium nitride (GaN) technology and applications at the upcoming PCIM Europe 2020 Digital Days, July 7 – 8. In addition, the company will participate in the event’s virtual exhibit, showing its latest eGaN FETs and ICs in customers’ end products that are rapidly adopting eGaN technology.

Why these chips are gaining ground, and what still needs to be addressed. Suppliers of gallium nitride (GaN) and silicon carbide (SiC) power devices are rolling out the next wave of products with some new and impressive specs. But before these devices are incorporated in systems, they must prove to be reliable.

EPC has posted additional modules to the educational video podcast series focusing on reliability and leading-edge applications including high-density computing for Artificial Intelligence (AI), lidar for robots, drones, and cars, and Class-D audio using gallium nitride FETs and ICs.

EL SEGUNDO, Calif. – April 2020 – Efficient Power Conversion (EPC) Corporation has posted an update to its popular “How to GaN” video podcast series. The six videos included in the current release of the series provide practical examples to help designers employ GaN technology to create state-of-the-art DC-DC converters for AI servers and ultra-thin laptops, lidar for robots, drones, and autonomous cars, and audio systems with the highest quality acoustics possible.

Three years ago, the cost of making medium voltage eGaN FETs fell below the cost of equivalently rated power MOSFETs. At that time EPC decided to use the performance and cost advantages of eGaN FETs to aggressively pursue applications with input, or output, voltage around 48 V. Specifically, automotive and computer applications is where 48 V conversion is becoming the new architecture, the new standard for power systems.
