The EPC9141 demonstration board is a 12 V output, 400 kHz buck converter with a 10 A maximum output current and 30 V to 54 V input voltage range (48 V nominal). The demonstration board features the EPC2045 (EPC2204 is the recommended replacement) enhancement mode (eGaN®) FETs, as well as the LTC7800 Buck controller.
The EPC9141 board contains the complete power stage (including eGaN FETs, controller, inductor and input/output caps) in a compact 25 mm x 33 mm layout to showcase the performance that can be achieved using the eGaN FETs and a traditional MOSFET controller together.
The EPC9141 demonstration board is 2.5 inch² (64 mm²) and contains a fully closed-loop buck converter with optimized control loop. GaN
