Design files

Overview

The PMP5327 reference design provides a 42V/6A output with power factor correction from a universal AC input voltage range. This design uses the UCC28019A to control the front end PFC boost stage. The output of the PFC is followed by a UCC25600 LLC resonant half-bridge. The total efficieny, from input to output is over 92% from a 230VAC input and over 89% from a 115VAC input. An additional 12V/250mA output is also generated by this supply.
