Product Preview
Power Factor Controller for
Compact and Robust,
Continuous Conduction
Mode Pre−Converters
(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.
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.

... DETAILED OPERATING DESCRIPTION Introduction The NCP1654 is a PFC driver designed to operate in fixed frequency, continuous conduction mode. The fixed frequency operation eases the compliance with EMI standard and the limitation of the possible radiated noise that may pollute surrounding systems. In addition, continuous conduction operation reduces the application dI/dt and their resulting interference ...
