Efficient Power Conversion Corporation (EPC) introduces the EPC9118, a fully-functional buck power conversion demonstration circuit. This 400-kHz buck converter board uses an input of 30- to 60-V and delivers a 5-V, 20-A maximum output current. It features the EPC2001 and EPC2015 enhancement-mode (eGaN®) field effect transistors (FETs), as well as the LTC3891 buck controller. This buck converter design is designed for distributed power solutions in telecom, industrial, and medical applications.

The EPC9118 board contains the complete power stage (including eGaN FETs, driver, inductor and input/output caps) in a compact 1” x 1.3” layout to showcase the performance that can be achieved using the eGaN FETs and a traditional MOSFET controller together. The EPC9118 demonstration board is 2.5” square and contains a fully closed loop buck converter with optimized control loop.
