The JW1515HA is a controller for offline flyback with GaN, which features quasi-resonant (QR) operation. QR control improves efficiency by reducing switching loss and benefits EMI performance with nature frequency variation. An internal frequency limitation is utilized to overcome the inherent disadvantages of QR flyback. The JW1515HA combines PWM and PFM control at different input and load condition for highest average efficiency. The JW1515HA comprises a HV pin for startup to eliminate conven.
