NCL2801 Power Factor Controller, High Efficiency
Power Factor Controller, High Efficiency, Enhanced for Lighting NCL2801 The 8pin PFC controller NCL2801 is designed to drive PFC boost stages. It is based on an innovative Valley Count Frequency Foldback VCFF method. The circuit classically operates in Critical conduction Mode CrM for high load values. When the load decreases a Discontinuous Conduction Mode DCM is forced by forcing a
