3 Description
The UCC28782EVM-030 is a 65-W USB-C PD 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 UCC28782EVM-030 converts input voltage of 90-V
