NCP1651 Single Stage Power Factor Controller The NCP1651 is an active, power factor correction controller that can operate over a wide range of input voltages.
It is designed for 50/60 Hz power systems.
It is a fixed frequency controller that can operate in continuous or discontinuous conduction modes.
The NCP1651 provides a low cost, low component count solution for isolated AC−DC converters with mid−high output voltage requirements.
The NCP1651 eases the task of meeting the IEC1000−3−2 harmonic requirements for converters in the range of 50 W − 250 W.
The NCP1651 drives a flyback converter topology to operate in continuous/discontinuous mode and programs the average input current to follo...
