Description

The UCG28846DREVM-151 is a 65W USB-C PD evaluation module (EVM) for evaluating an off-line GaN integrated quasi-resonant flyback converter for AC/DC adapters, chargers, USB wall outlets, and other applications. The EVM meets CoC Tier 2 and DoE Level 6 efficiency requirements. The EVM is intended for evaluation purposes and is not intended as a product. The UCG28846DREVM-151 converts input voltage of 90VRMS to 264VRMS down to a selectable USB-C PD output voltage of 5VDC, 9VDC, 15VDC, or 20VDC. This EVM can also be configured to produce a fixed output voltage in the range from 5VDC to 24VDC. The EVM is designed to deliver 3.00A of maximum output current up to 15VDC and 65W of maximum output power for the output voltage above 15VDC up to 24VDC. The main device used in this design is the UCG28846 with integrated 750V GaN FET and controller in 3.9mm × 9.9mm package.
