General Description
BD7690FJ is Power Factor Correction for AC/DC supplies the system which is suitable for all the products needing power factor improvement. The PFC adopts boundary conduction mode (BCM), and switching loss reduction and noise reduction are possible by Zero Current Detection (ZCD). ZCD is detected by auxiliary winding.

Features
■ Boundary Conduction Mode
■ Low Power consumption
■ VCCUVLO
■ The ZCD detection by auxiliary winding
■ Switching loss reduction, noise reduction by ZCD
■ Improving the efficiency by the max frequency control
■ Dynamic and Static OVP by the VS pin
■ High accuracy over current detection(±4%)
■ Error amplifier input short protection
■ Restart timer
■ Stable MOSFET gate drive by the Clamper

Applications
■ AC adopter, TV, Lighting equipment, Refrigerator, etc.
