Infineon Technologies ICE5GR4780AG | Demoboard REF_5GR4780AG_6W1

6 W auxiliary power supply using ICE5GR4780AG

Overview

TopologyFlyback Converter
Switching frequency125 kHz
Output 112 V / 0.5 A
IC revisionV1.0

Description

The REF_5GR4780AG_6W1 is an auxiliary power supply reference design based on Infineon’s 5th generation fixed-frequency CoolSET™ family (ICE5GR4780AG) configured in a flyback topology. It utilizes a simple Zener diode reference voltage for the feedback loop and a simple input Pi filter for EMI suppression to support cost performance auxiliary power supply targeting small home appliances.

Features

  • 125kHz maximum switching frequency with 800V integrated MOSFET
  • Power delivery of up to 15W with universal wide input range (85~300VAC) DCM design
  • Brown in protection, fast and robust start-up operation with cascode configuration
  • 3 level selectable entry/exit active burst mode profile (optional)
  • Built-in digital soft-start
  • Cycle by cycle peak current limitation
  • Support both DCM and CCM operation with slope compensation
  • Integrated error amplifier to support direct feedback typical with non-isolated flyback topology
  • Digital frequency reduction with decreasing load for higher efficiency
  • Adjustable line input over voltage protection (optional)
  • VCC pin short to ground protection
  • OLP, output short, OTP with hysteresis and VCC over/under voltage protection
  • Auto-restart for all protection features

Typical applications

  • Offline aux SMPS for server, PC power, aircon, refrigerator and audio, Offline main SMPS for adapter, set-top-box, water purifier, TV, industrial SMPS and POE
