Design files

Overview

The PMP5967 reference design provides a 12V/38A output with over 94% efficiency from a 380VDC input. This design uses the UCC25600 to control the resonant LLC converter. The UCC24610 synchronous rectifier controller is used to control two banks of CSD18501Q5A MOSFETs, eliminating the need for heat sinks on the output rectifiers.
