By EPC 494
EPC's EPC9118 demonstration board is a 5 V output, 400 kHz buck converter with a 20 A maximum output current a 30 V to 60 V input voltage range. The complete power stage, including the EPC2001 and EPC2021 eGaN® FETs, driver, inductor and input/output caps, is in an ultra 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 1/2" square and contains a fully closed-loop buck converter with optimized control loop. Despite its small size, the board has peak power efficiency greater than 93%, capable of delivering 20 A at 5 V with a 36 V input.
