Infineon Technologies ICE5QR2280BG

Beschreibung

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.
