STMicroelectronics 45 W QR USB PD Adapter reference design based on VIPERGAN50 and STUSB4761 Power Supply for

The STMicroelectronics 45 W USB type C power delivery 3.0 adapter , which is a USBPD reference design solution. It is an isolated power supply based on the VIPERGAN50, a new offline high voltage converter from the VIPerPlus family with a 650 V HEMT Power GaN transistor, designed for quasi resonant flyback converters and capable of providing an output power up to 50 W in wide range. 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.
