NCP1654BD65R2G
RoHS 10 Compliant
The NCP1654BD65R2G is a Power Factor 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. 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.
