Continuous Conduction Mode PFC IC FA5614N / FA5615N Datasheet 1. Overview FA5614/15 is control IC for power factor correction converter. It realizes low power consumption by using high voltage CMOS process. Thanks to a average current control, a stable operation is obtained, whereby a power factor of 99% or more is easily available. DC output voltage is controlled under a wide range of load from rated to no load. Further, a unique switching frequency diffusion function incorporated simplifies the line filter. 2. Features ▪ Unique switching frequency diffusion function incorporated ▪ Selectable switching frequency : Diffuse or Fix (120 kHz, 130 kHz) ▪ High-precision over current protection : 0.
