NCP1650
Power Factor Controller
The NCP1650 is an active, power factor correction controller that
can operate over a wide range of input voltages, and output power
levels. It is designed to operate on 50/60 Hz power systems. This
controller offers several different protection methods to assure safe,
reliable operation under any conditions.
The PWM is a fixed frequency, average current mode controller
with a wide complement of features. These features allow for both
flexibility as well as precision in it’s application to a circuit. Critical
components of the internal circuitry are designed for high accuracy,
which allows for precise power and current limiting, therefore
minimizing the amount of overdesign necessary for the power stage
components.
The NCP1650 is designed with a true power limiting circuit that will
maintain excellent power factor even in constant power mode. It also
contains features that allow for fast transient response to changing
load currents and line voltages.
