BD7691FJ
Power Factor Correction Controller IC

BD7691FJ 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.
