EPC's chief executive, Alex Lidow, believes his GaN devices now beat silicon on performance and price, reports Rebecca Pool.
For EPC chief executive, Alex Lidow, this year's PCIM Europe 2019 has been all about applications. Presenting myriad enhanced-mode GaN FETs and ICs in end-products, the company is making a big play for 48 V DC-DC power conversion in advanced computing and automotives.
The increase in switching speed offered by GaN transistors requires good measurement technology, as well as good techniques to capture important details of high-speed waveforms. This article focuses on how to leverage the measurement equipment for the user’s requirement and measurement techniques to accurately evaluate high performance GaN transistors. The article also evaluates high bandwidth differential probes for use with non-ground-referenced waveforms.

EPC9107 demonstrates size reduction and efficiency enhancement for power conversion achieved using high frequency switching eGaN power transistors
EL SEGUNDO, Calif.—June, 2013 — Efficient Power Conversion Corporation (EPC) introduces the EPC9107, a fully functional buck power conversion demonstration circuit. This board is a 9 V-28 V input to 3.3 V, 15 A maximum output current, 1MHz buck converter. It uses the EPC2015< eGaN FET in conjunction with the LM5113 100V half-bridge gate driver from Texas Instruments. The EPC9107 demonstrates the reduced size and ...
eGaN FETs differ from silicon MOSFETs in part because of their significantly faster switching speeds. In the second article of this series, we explore the different requirements for gate drive, layout, and thermal management.
