General Description

Key Specifications

BD7693FJ and BD7694FJ are Power Factor Correction

IC 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). This IC incorporates a

circuit lowering total harmonics distortion (THD) and can

support IEC61000-3-2 Class-C.
