Description
The EVLVIPGAN50WP 45 W USB Type-C® Power Delivery 3.0 adapter is a USBPD reference design solution. It is an isolated power supply based on the VIPERGAN50W, a new offline high-voltage converter from the VIPERGAN family with a 700 V HEMT Power GaN transistor, designed for quasi-resonant flyback converters, capable of providing an output power up to 50 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. This controller offers the benefits of a full hardware USB PD stack allowing robust, deterministic and safe negotiation in line with USB PD standard.The evaluation board implements a robust adapter protected for output overvoltage, output undervoltage, output over power and output short-circuit. This reference design, based on STMicroelectronics semiconductors, helps designers to develop adapters with a short bill of materials to obtain a cost-effective and fast design.
