Product details

Overview

EVLVIPGAN50FL from STMicroelectronics is an evaluation board implementing a 15 V / 50 W quasi-resonant (QR) isolated flyback converter using the VIPERGAN50 GaN-based controller, supporting universal AC input (90–265 VAC, 50/60 Hz), achieving >90% average efficiency and <85 mW standby consumption at 230 VAC, deployed in industrial power supplies and smart home AC-DC adapters.

For engineers reviewing the EVLVIPGAN50FL datasheet, EVLVIPGAN50FL pinout, EVLVIPGAN50FL application, or EVLVIPGAN50FL equivalent, this page delivers verified board-level specifications, functional architecture, design-integrated protections (input OVP, brown-in/out, output OVP, OCP LEB, thermal shutdown), and real-world implementation details for rapid prototyping and compliance validation.

Technical Context

The EVLVIPGAN50FL implements a QR flyback topology with valley-lock synchronization and adaptive burst mode, enabling high efficiency across full line/load range. It integrates VIPERGAN50 - a 650 V PowerGaN device with embedded Si senseFET and HV startup - eliminating external startup circuitry and reducing BOM count.

EMI suppression is achieved via frequency jittering, allowing Class B compliance per IEC55022 with a reduced pi-filter. Input voltage feedforward ensures mains-independent over-power protection (OPP), while dynamic blanking time and adjustable valley sync delay optimize switching timing under varying conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	90–265 VAC, 50/60 Hz - supports global mains without manual selection or hardware reconfiguration.
Output Voltage	15 V ±1% - tightly regulated for powering logic, gate drivers, or auxiliary rails in industrial systems.
Output Power	50 W continuous - sufficient for mid-power IoT gateways, PLC I/O modules, and LED driver control stages.
Average Efficiency	>90% at full load - reduces thermal stress and enables compact heatsink-free designs in enclosed enclosures.
Standby Consumption	<85 mW at 230 VAC - meets stringent EU CoC v5 Tier 2 and Energy Star requirements.
EMI Compliance	IEC55022 Class B - achieved with minimal external filtering due to integrated frequency jittering.
Protections	Input OVP/brown-in/out, output OVP, overload, OCP LEB, thermal shutdown - all settable or embedded for field-reliable operation.

FAQ

What is the primary function of the EVLVIPGAN50FL evaluation board?

The EVLVIPGAN50FL is a complete 15 V / 50 W quasi-resonant flyback evaluation board built around the VIPERGAN50 GaN controller. It demonstrates a production-ready, EMI-compliant AC-DC conversion solution with integrated protections, synchronous rectification, and adaptive light-load management - intended for design-in validation and performance benchmarking.

Does the board include both primary and secondary side components?

Yes. The EVLVIPGAN50FL comprises a mainboard (primary-side: diode bridge, EMI filter, VIPERGAN50, flyback transformer) and a daughterboard (secondary-side: synchronous rectifier MOSFET Q2, output capacitors C2/C18/C27, feedback network). Schematics for both are provided in DB4818 Rev 2 Figures 1 and 2.

Can the output voltage be adjusted, and how is output OVP configured?

The nominal output is fixed at 15 V by the feedback resistor divider (R3/R5 on daughterboard). Output OVP is settable via external resistors connected to the FB pin - configuration details and threshold calculation are specified in the VIPERGAN50 datasheet (Section 8.3.2) and validated in the EVLVIPGAN50FL schematic.

Is the VIPERGAN50 controller accessible for firmware or configuration changes?

No. VIPERGAN50 is a fully integrated, hard-wired analog controller - not programmable or configurable via digital interface. All operating parameters (valley sync delay, burst threshold, OPP level) are set by external passive components per the application schematic and datasheet design guidelines.
