NCL2801 High-Efficiency Power Factor Controller

DATA SHEET www.onsemi.com Power Factor Controller, High-Efficiency, Enhanced for Lighting 8 1 SOIC 8 CASE 751 NCL2801 The 8 pin PFC controller NCL2801 is designed to drive PFC boost stages. It is based on an innovative Valley Count Frequency Fold back (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 dead time which, by construction c.
