BD7690FJ
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
