UCC28600EVM

UCC28600 AC to DC Switching Converter 19VDC to 19.8VDC Output Evaluation Board

is an evaluation module for UCC28600 which is 120W off line quasi resonant flyback converter providing a 19.4V regulated output at 6.2A of load current, operating from a universal ac input. The front end power factor correction PFC stage is controlled by the UCC28051 and accommodates an input line voltage range of 85VRMS to 265VRMS and is designed to meet EIC61000-3-2 harmonic emissions requirements. The module uses the UCC28600 quasi resonant flyback green mode controller which integrates built in state of the art energy saving features with high level protection features to provide cost effective solutions for energy efficient power supplies. A dedicated STATUS pin is used to disable the PFC controller when the converter has entered standby.
