Descrizione
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.
