EPC9131: 27 W, 19 V Regulated SEPIC Converter

EPC9131: 14 VIN - 48 VIN to 19 VOUT SEPIC Converter Using EPC2112

EPC9131 Development Board

The EPC9131 demonstration board is a 19 V output, 300 kHz single-ended primary-inductor converter (SEPIC) with a 27 W maximum output power and 14 V to 48 V input voltage range.

The EPC9131 board contains the complete power stage (including eGaN IC, driver, inductors and input/output capacitors) in a compact 25 mm x 33 mm layout to showcase the performance that can be achieved using the EPC2112 eGaN IC. It also contains a closed-loop SEPIC with optimized control loop.
