BD7693FJ (New)
Power Factor Correction Controller IC

BD7693FJ is 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.
