Product overview
Description
The STDES-VIPGAN65F is 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.
At the secondary side, to increase the system efficiency, the rectification is based on the SRK1004 adaptive synchronous rectification controller.
Also on the secondary side, the CC/CV regulation loop drives 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 standards.
The evaluation board implements a robust adapter protected for output overvoltage, output undervoltage, output overpower 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.
