This design document describes a 65-W USB-C PD evaluation module which converts a universal input voltage of 90-VRMS to 264-VRMS down to 5 V, 9 V, 12V, 15 V and 20 V. This featured power supply is an active-clamp flyback topology utilizing Texas Instrument’s UCC28782 controller, and WiseGaN Half Bridge WI62175. This design note provides complete circuit schematic, PCB, BOM and transformer information of the evaluation board. It also provides efficiency and thermal data of the evaluation board. Active-clamp flyback topology effectively recycles the leakage energy. Another feature of this topology is the ZVS operation of the power transistors. Because of no leakage losses and ZVS operation, this topology is suited for high frequency operation which results in size reduction of the transformer. A ZVS fixed switching frequency power converter also simplifies EMI design and can be easily designed to avoid interference with other sensitive circuits in the system.
