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 IE
