The UCC28780EVM-021 is a 45-W evaluation module (EVM) for evaluating an off-line active-clamp flyback adapter for notebook charging and other applications. The EVM meets CoC Tier 2 and DoE Level 6 efficiency requirements. It is intended for evaluation purposes and is not intended to be an end product. The UCC28780EVM-021 converts input voltage of 90-VRMS to 264-VRMS down to 20-VDC, with a 2.25-A nominal output current rating and a 160-ms limit for over-power capability. The main devices used in this design are active clamp flyback controller UCC28780, SR controller UCC24612, and Si MOSFETs.
