STMicroelectronics EVLVIPGAN100PD

Overview

EVLVIPGAN100PD from STMicroelectronics is a 100 W USB Type-C® Power Delivery 3.0 reference design evaluation board implementing a quasi-resonant flyback converter with GaN-based VIPERGAN100 primary-side controller, L6564 transition-mode PFC, SRK1001 synchronous rectification, and STUSB4761 hardware-based PD stack - delivering five fixed PDOs (5–20 V) and >92.6% peak efficiency for compact AC-DC adapters.

For engineers reviewing the EVLVIPGAN100PD datasheet, EVLVIPGAN100PD pinout, EVLVIPGAN100PD application, or EVLVIPGAN100PD equivalent, this board serves as a production-ready reference for designing cost-optimized, high-power-density USB PD chargers compliant with USB PD 3.0, CC/CV regulation, and full hardware negotiation - with integrated OVP/UVP/OPP/SCP protection.

Technical Context

The design integrates three key ICs: VIPERGAN100 (650 V GaN HVC + PWM controller in one package) drives the quasi-resonant flyback stage with optocoupler feedback; L6564 enables active PFC with <5% THD across universal AC input (90–264 VAC, 47–63 Hz); STUSB4761 provides deterministic, standards-compliant USB PD negotiation via dedicated CC1/CC2 interface and programmable VBUS control.

Secondary-side regulation combines SRK1001 adaptive synchronous rectification (up to 300 kHz) with hardware CC/CV loop management, while protection logic monitors Vsense, Isense, and Fault signals to enforce output overvoltage (18 V clamp), undervoltage, overpower, and short-circuit limits - all implemented without firmware dependency.

FAQ

What is the role of the VIPERGAN100 IC in this reference design?

VIPERGAN100 integrates a 650 V GaN power switch, high-voltage startup cell, and low-voltage PWM controller in one package. It implements the primary-side quasi-resonant flyback control with ZCD sensing and optocoupler feedback - enabling high-efficiency, low-EMI operation at up to 100 W while minimizing external component count.

Does EVLVIPGAN100PD support programmable power supply (PPS)?

No. EVLVIPGAN100PD implements only fixed PDOs per USB PD 3.0 specification: 5 V, 9 V, 12 V, 15 V, and 20 V - each with defined current limits. It does not include PPS negotiation capability, as STUSB4761 is configured for fixed-profile operation in this design.

How is USB Type-C cable detection and orientation handled?

Cable orientation and CC line detection are managed by the STUSB4761 controller via dedicated CC1 and CC2 pins. The IC autonomously identifies plug insertion, polarity, and sink/source role - then configures VBUS enable, VCONN, and power contract accordingly using its embedded hardware PD stack.

Can this board be used for production, or is it evaluation-only?

EVLVIPGAN100PD is an evaluation board intended for design verification and reference implementation - not certified for end-product compliance (e.g., UL/CE). While its topology and BOM are production-relevant, final certification requires re-engineering for safety isolation, EMI filtering, and regulatory testing per target market requirements.
