Description

The NCP1654 is a controller for Continuous Conduction Mode (CCM) Power Factor Correction Step up preconverters. It controls the power switch conduction time (PWM) in fixed frequency mode and is dependant on the instantaneous coil current. Housed in a SO-8 package the circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuit.
