USB Type-C™ Power Delivery ViperGaN65 Reference Design

65 W, based on VIPERGAN65 and STUSB4761

Featuring the EVLVIPGAN65PD by STMicroelectronics – a 65 W USB Type-C® Power Delivery 3.0 adapter reference design.

It is an isolated power supply with a standalone USB PD controller. The evaluation board implements at the primary side a quasi-resonant flyback converter based on the VIPERGAN65 HV converter with optocoupler feedback for voltage regulation.

This controller combines a high performance low-voltage PWM controller chip with a 650 V HV startup cell in the same package. The advanced power management with the low quiescent helps to achieve low standby consumptions.
