Boundary Conduction Mode

Power Factor Correction Controller IC

BD7692FJ

General Description

Key Specifications

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.
