Datasheet - NCP1680ABD1R2G

The ON Semiconductor series NCP1680 is a CRM 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.

Totem Pole PFC Topology Eliminates Input Diode Bridge
