UCC28950EVM-442, 600-W, Phase-Shifted, Full-Bridge Converter Evaluation Module

UCC28950EVM-442 is a 600-W phase-shifted full-bridge converter that converts a 370 V to 410-V DC input to a regulated 12-V output. This converter was designed to maintain ZVS down to 50% load. This 600-W EVM was designed to demonstrate how the UCC28950 control device could be used in high-efficiency applications by achieving ZVS from 50% to 100% load. To achieve this high efficiency the UCC28950 was designed to drive synchronous rectifiers on the secondary side of the full bridge converter. The UCC28950 also incorporates a burst mode and DCM function to improve no-load efficiency
