The ON Semiconductor NCP series of a PFC controller IC designed to drive the bridgeless totem-pole PFC topology. The bridgeless totem-pole PFC is a power factor correction architecture that consists of a fast switching leg driven at the PWM switching frequency and a second leg that operates at the AC line frequency. This topology eliminates the diode bridge present at the input of a conventional PFC circuit, allowing significant improvement in the power stage efficiency.
Enables high efficiency & compact design
Skip mode in very light load condition
Near unity power factor in all operating modes
Prevents operation in audible range
