JW1565J is an isolated offline flyback PWM converter with GaN integrated, which

quasi-resonant (QR) operation. QR control improves efficiency by reducing switching loss and benefits EMI performance with nature frequency variation. An internal maximum frequency limitation is utilized to overcome the inherent disadvantages of QR flyback. JW1565J comprises a HV pin for start-up to eliminate conventional start-up resistors and save standby mode energy consumption. It can comply with the most stringent efficiency regulations. Also, the HV pin is used for X-cap discharge when AC.
