STMicroelectronics VIPERGAN50 | Demoboard EVLVIPGAN50PD
EVLVIPGAN50PD - 45W USB PD adaptor reference design with VIPERGAN50
Overview
| Topology | USB |
| Input voltage | 90-264 V |
| Output 1 | 20 V |
| IC revision | 1 |
Description
This document reports the functional, thermal, and efficiency measurement results for the EVLVIPGAN50PD 45 W QR mode flyback adaptor reference design for USB Type-C™ PD adaptors. This reference design meets CoC Tier 2 and DoE Level 6 efficiency requirements with peak efficiency of 92.4% at full load.The evaluation board implements at the primary side a quasi-resonant flyback converter based on the VIPERGAN50 controller with optocoupler feedback for voltage regulation. The main devices used in this reference design are:VIPERGAN50: 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 low quiescent helps to achieve low standby consumptions.SRK1001 and STL110N10F7: to increase the system efficiency, the rectification is based on the SRK1001 adaptive synchronous rectification controller. The SRK1001 drives the gate of the 100 V STripFET F7 technology power MOSFET STL110N10F7.STUSB4761: this controller offers the benefits of a full hardware USB PD stack allowing robust, deterministic, and safe negotiation in line with the USB PD standard.The EVLVIPGAN50PD is a fully assembled kit intended for performance evaluation only, not an end product for sale.
