The UCG28826EVM-093 is a 65W USB-C® PD evaluation module (EVM) for evaluating an off-line GaN integrated quasi-resonant flyback adapter for AC/DC adapters, chargers, USB wall outlets, and other applications. The EVM meets CoC Tier two and DoE Level six efficiency requirements. The EVM is intended for evaluation purposes and is not intended to be an end product. The UCG28826EVM-093 converts input voltage of 90VRMS to 264VRMS down to a selectable USB-C PD output voltage 20VDC, with a max 3.25A, and to 5VDC, 9VDC, and 15VDC, with a max 3.00A output current rating. The main device used in this design is the UCG28826 with integrated 650V GaN FET and controller in 5mm x 5mm package.
Features
- 93-95% efficiency under full-load operation over entire input voltage range.
- 2.8W/cm3 (3.9cm x 3.43cm x 1.71cm) power density enabled by 140kHz maximum switching frequency.
- Self-bias and auxless-sense, Integrated current sense, integrated HV startup and integrated X-cap discharge enable lowest BOM cost by integration.
- Comprehensive protection features including OVP, OTP, Short circuit and overcurrent protection and brown-in/out protection.
- USB-C output enables full system-level evaluation for end-equipments like ADAP.
