TDADP-TPH-ON-USBC-100W-RD

Open Frame 100 W USB-C PD/PPS Power Adapter Reference Design using Transphorm SuperGaN Technology

The TDADP-TPH-ON-USBC-100W-RD is an open frame 100 W universal USB-C Power Delivery (PD) power adapter reference design. It meets USB PD 3.0 requirements for universal chargers supporting smartphones, laptops and other IoT devices. The power supply uses the ON Semi PFC controller (NCP1623) and the Quasi Resonant Flyback (QRF) PWM controller (NCP1342) with variable frequency control up to 300 kHz; Transphorm's TP65H150G4LSG (650 V, 150 mΩ GaN FET), TP65H300G4LSG (650 V, 240 mΩ GaN FET); and Weltrend’s WT6633P USB PD controller. This design enables high power density (~18 W/in3) and over 92 percent efficiency at fullpower.
