1 page ![]() © Semiconductor Components Industries, LLC, 2009 June, 2009 − Rev. 3 1 Publication Order Number: NCP1654/D NCP1654 Power Factor Controller for Compact and Robust, Continuous Conduction Mode Pre-Converters The NCP1654 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 implementation. It also integrates high safety protection features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry.
