bd7695fj-凯发k8一触即发
power factor correction controller icbd7695fj is 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.
