EPC9101 demonstrates size reduction and efficiency enhancement for buck power conversion achieved using high frequency switching eGaN power transistors
EL SEGUNDO, Calif.—October 2011 — Efficient Power Conversion Corporation (EPC) introduces the EPC9101, a fully functional buck power conversion demonstration circuit. This board is an 8 V-19 V input to 1.2 V, 18 A maximum output current, 1MHz buck converter. It uses the EPC2014 and EPC2015 eGaN FETs in conjunction with the recently introduced National LM5113 100V half-bridge gate driver from Texas Instruments. The LM5113 is the industry’s first driver designed specifically for enhancement mode gallium nitride FETs. The EPC9101 demonstrates the reduced size and performance capabilities of high switching frequency eGaN FETs when coupled with this dedicated eGaN driver.
