Description

This document is an engineering report that describes a universal-input 24 W 12 V 5 V off-line Flyback converter using the newest fifth-generation Infineon Quasi-Resonant (QR) CoolSET™ ICE5QR2280BG. It offers high-efficiency, low-standby power with selectable entry and exit standby power options, a wide VCC operating range with fast start-up, robust line protection with input Over-Voltage Protection (OVP), and brown-out and various modes of protection for a highly reliable system. This demo board is designed for users who wish to evaluate the performance of ICE5QR2280BG and its ease-of-use.

Features

Novel quasi-resonant switching scheme
Rapid and adjustable start-up with cascode configuration
2 level selectable active burst mode level
Built-in digital soft-start
Cycle by cycle peak current limitation
Digital frequency reduction with decreasing load for higher efficiency
Adjustable line input over-voltage and brown IN/OUT protection
VCC pin short to ground protection
OLP, output short, output over-voltage, 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
