Overview

PMP20660 is a synchronous 4-switch buck-coost converter reference design using the LM5175 controller IC. The converter accepts an input voltage of 5Vin to 13Vin and provides a constant-voltage/constant-current output of 12Vout and approximately 11A. The reference design is built on the LM5175EVM-HP evaluation board which is a 6-layer FR-4 PCB, with 2 oz. copper for each of the six layers.

Features
  • Synchronous operation for high efficiency
  • Constant current and constant voltage control
  • Output voltage can be above or below input voltage
  • Enables quick charging of supercapacitors
