Boundary Conduction Mode
Power Factor Correction Controller IC
BD7692FJ
General Description
BD7692FJ 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 detects by resistance, the
auxiliary winding is unnecessary.
