Texas Instruments UCG28836EVM-150 Evaluation Module (EVM)
Texas Instruments UCG28836EVM-150 Evaluation Module (EVM) is a 65W USB-C® PD evaluation module for evaluating an offline GaN-integrated quasi-resonant flyback converter for AC-DC adapters, chargers, USB wall outlets, and other applications. The evaluation module meets CoC Tier 2 and DoE Level 6 efficiency requirements. The evaluation module is intended for evaluation purposes and is not intended as a product.
The UCG28836EVM-150 converts input voltages from 90VRMS to 264VRMS to a selectable USB Type-C PD output voltage of 5VDC, 9VDC, 15VDC, or 20VDC. This evaluation module can also be configured to produce a fixed output voltage in the range from 5VDC to 24VDC. The Texas Instruments UCG28836EVM-150 is designed to deliver a maximum output current of 3.00A at up to 15VDC and a maximum output power of 65W at output voltages above 15VDC up to 24VDC.
The main device used in this design is the UCG28836, with an integrated 750V GaN FET and controller, in a 5mm × 5mm package.
