JW1520AH Overview
FEATURES The JW1520AH is an offline CV and CC Flyback power switch with primary-side regulation (PSR), which features quasi-resonant (QR) operation for all operation modes. QR control improves efficiency by reducing the switching loss and also benefits EMI performance with nature frequency variation. The JW1520AH bines PWM and PFM control at different input and load condition for highest average efficiency.
