UCC28600 120-W Evaluation Module User's Guide (Rev. A)

The UCC28600 evaluation module (EVM) is a 120-W off-line quasi-resonant flyback converter providing a 19.4-V regulated output at 6.2 A 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 85 VRMS to 265 VRMS 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.
