General Description

BD7695FJ and BD7696FJ are Power Factor Correction

ICs for AC/DC supply, which are suitable for all 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). This IC incorporates a circuit for

reducing total harmonics distortion (THD) and can

support IEC61000-3-2 Class-C.
