Overview

PMP6712 is a phase-shifted full-bridge converter capable of delivering 1600W of isolated output power and achieving efficiency of greater than 96%. This design uses the UCC28950 controller in a dual phase master-slave configuration. An LM5017 constant on-time synchronous buck regulator provides bias power to primary and secondary-side circuits using a coupled inductor with isolated flyback winding. The isolation voltage is specified as 2250VDC, allowing this design to be used as a system supply for Power Over Ethernet and other telecommunications applications.
