JW1515H Overview
Description
The JW®1515H is a controller for offline flyback with GaN, which features quasi-resonant (QR) operation. QR control improves efficiency by reducing switching loss and also benefits EMI performance with nature frequency variation, and an internal frequency limitation to overcome the inherent disadvantages of QR flyback.
