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 stepup preconverters. 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.
