PMP20808 is a single-phase synchronous cuck converter reference design using the LM5117 controller IC. The design accepts an input voltage of 36Vin to 40Vin (38Vin Nominal) and provides an output of 25Vout capable of supplying 18A of continuous current to the load. The design was built on the PMP9280 PCB, which was modified to the PMP20808 design configuration and requirements. The PCB is a 4-layer board with 1oz copper on all layers.
Features
- Very high efficiency and high power
- Small solution size for its voltage and power
- Only single-phase operation
- Optional current monitor output
