JW1566A Datasheet | JoulWatt Technology

DESCRIPTION The JW®1566A is an isolated offline Flyback converter with Ga N 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 overe the inherent disadvantages of QR Flyback. The JW1566A bines PWM and PFM control at different input and load condition for highest average efficiency. It can ply with the most stringent efficiency regulations. FEATURES - Integrated 650V 400mΩ Ga N - Wider VDD Operation Range (Up to 90V) - QR Operation for High Efficiency - Maximum 260k Hz Switching Frequency - Optional OCP and OPP Function for Different PD and QC Output Application - Very Low Standby Power Consumption - Cycle-by-Cycle Current Limit - Reliable Fault Protections: VDD OVP, VS OVP and UVP, Brown-In, CS Open Protection, OCP, OPP, Internal OTP - Frequency Jitter to Ease EMI pliance - DFN5X6-7 Package The JW1566A is available in the 5mm- 6mm DFN package. The high level of integration results in a simple to use, low ponent count, and high efficiency application solution for isolated power delivery. pany’s Logo is Protected, “JW” and “JOULWATT” are Registered Trademarks of Joul Watt technology Inc.
