EPC9005 demonstrates the ease of designing with eGaN FETs with ready-made, easy to connect development boards and well-documented engineering support materials.
EL SEGUNDO, Calif.—April 2013— Efficient Power Conversion Corporation (EPC) today announces the availability of the EPC9005 development board, featuring EPC’s enhancement-mode gallium nitride (eGaN) field effect transistors (FETs). This board demonstrates how IC gate drivers, optimized for eGaN FETs, make the task of transitioning from silicon to eGaN technology simple and cost effective.

Texas Instruments Incorporated (TI) introduced a low-side gate driver for use with MOSFETs and Gallium-Nitride (GaN) power field-effect transistors (FETs) in high-density power converters. The new LM5114 drives GaN FETs and MOSFETs in low-side applications, such as synchronous rectifiers and power factor converters. Together with the LM5113, the industry's first 100-V half-bridge GaN FET driver announced in 2011, the family provides a complete isolated DC/DC conversion driver solution for high-power GaN FETs and MOSFETs used in high-performance telecom, networking and data center ...
We know Efficient Power Conversion (EPC) has commercialized enhancement-mode GaN-on-Si FETs, or eGaN FETs as EPC calls them, for more than a year now. Concurrently, it has been working with partners to realize dedicated drivers for its eGaN FETs, which offer lower RDS(ON) at higher voltages, lower gate charge, and no reverse recovery loss (QRR)—all these properties from a smaller die size than silicon. In essence, by comparison to silicon MOSFETs, the eGaN FETs offer a dramatic reduction in figures of merit or FOM.

National Semiconductor Corp. (NYSE:NSM) today introduced the industry’s first 100V half-bridge gate driver optimized for use with enhancement-mode Gallium-Nitride (GaN) power field-effect transistors (FETs) in high-voltage power converters. Enhancement-mode GaN FETs enable new levels of efficiency and power density compared to standard metal-oxide semiconductor field-effect transistors (MOSFETs) due to their low on-resistance (Rdson) and gate charge (Qg) as well as their ultra-small footprint, but driving them reliably presents significant new challenges. National’s LM5113 ...
