Datasheet Summary
Power Factor Controller for pact 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 ponents and drastically simplifies the PFC implementation. It also integrates high safety protection Features that make the NCP1654 a driver for robust and pact PFC stages like an effective input power runaway clamping circuitry.
