EVLVIPGAN50PD QR USB PD Adapter Reference Design

STMicroelectronics' 45 W QR USB PD adapter reference design is based on VIPerGaN50 and STUSB4761

Image of STMicroelectronics' EVLVIPGAN50PD QR USB PD Adapter Reference DesignSTMicroelectronics' EVLVIPGAN50PD 45 W USB Type-C® Power Delivery 3.0 adapter is an isolated power supply based on the VIPERGAN50, an offline high-voltage converter from the VIPer family with a 650 V HEMT Power GaN transistor, designed for quasi-resonant flyback converters, capable of providing an output power up to 45 W in wide range. At the secondary side, to increase the system efficiency, the rectification is based on the SRK1001 adaptive synchronous rectification controller. Still on the secondary side, the CC/CV regulation loop to drive the power regulation stage and the USB Type-C PD interface is based on the STUSB4761 controller.

The evaluation board implements a robust adapter protected for output overvoltage, output undervoltage, output over power, and output short-circuit. Based on STMicroelectronics semiconductors, this reference design helps designers develop adapters with a short bill of materials to obtain a cost-effective, fast design.
