JW1515H - Offline QR GaN Flyback Controller

General Description

The JW®1515H is a controller for offline flyback with GaN, which

Key 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. The JW1515H combines PWM and PFM control at different input and load condition for highest average efficiency. The JW1515H comprises a HV pin for startup to eliminate conventional startup resistor and save standby mode energy consumption. It can comply.
