CRM Totem Pole PFC Controller IC
The BM85060FV is a critical conduction mode (CRM) power factor correction (PFC) controller IC designed to drive a bridgeless totem pole PFC topology. Bridgeless totem pole PFC consists of two totem pole legs: a fast-switching leg driven at high switching frequencies and a second leg operating at AC line frequency. This topology eliminates the need for a diode bridge, which is essential in conventional PFC circuits, and significantly improves efficiency and power density.
