Topology | Power Factor Correction |
IC revision | 1.1 |
The NCP1680 is a Critical Conduction Mode (CrM) Power Factor Correction (PFC) controller IC designed to drive the bridgeless Totem Pole PFC (TPFC) topology. The bridgeless totem pole PFC consists of two totem pole legs:a fast switching leg driven at the PWM switching frequency and a second leg that operates at the AC line frequency. Thistopology eliminates the diode bridge present at the input of a conventional PFC circuit, allowing significant improvement in efficiency and power density.
