UCC28780EVM-021 Converter Evaluation Module (EVM)

Texas Instruments UCC28780EVM-021 Converter Evaluation Module (EVM) evaluates an offline active-clamp flyback adapter for notebook charging and other applications. The evaluation module meets CoC Tier 2 and DoE Level 6 efficiency requirements. This evaluation module is intended for evaluation purposes and is not intended to be an end product. The Texas Instruments UCC28780EVM-021 converts input voltage of 90V_RMS to 264V_RMS down to 20VDC, with a 2.25A nominal output current rating and a 160ms limit for over-power capability. The main devices used in this design are active clamp flyback controller UCC28780, SR controller UCC24612, and Si MOSFETs.
