BM85060FV Overview
Description
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.
Key Features
- Critical conduction Mode (CrM) and Discontinuous Conduction Mode (DCM) Operation
- Burst Mode Operation at Very Light Loads
- Brownout Detection
- X Capacitor Discharge Function
- High Voltage Startup
