The NCP1654 Power Factor Controller is a controller for Continuous Conduction Mode (CCM) power factor correction step-up pre-converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current. Housed in a SO8 package, the circuit minimizes the number of external components and drastically simplifies the PFC implementatio
