JW1566A Offline QR GaN Flyback Converter

The JW®1566A is an isolated offline Flyback converter with GaN integrated, which features quasi-resonant (QR) operation. QR control improves efficiency by reducing switching loss and benefits EMI performance with nature frequency variation, and an internal maximum frequency limitation to overcome the inherent disadvantages of QR Flyback. The JW1566A combines.

Features

quasi-resonant (QR) operation. QR control improves efficiency by reducing switching loss and benefits EMI performance with nature frequency variation, and an internal maximum frequency limitation to overcome the inherent disadvantages of QR Flyback. The JW1566A combines PWM and PFM control at different input and load condition for highest average efficiency. It can comply with the most stringent efficiency regulations. FEATURES
