NCP1612A, NCP1612B, NCP1612A1, NCP1612A2, NCP1612A3, NCP1612B2 Enhanced, High‐Efficiency Power Factor Controller The NCP1612 is designed to drive PFC boost stages based on an innovative Current Controlled Frequency Fold-back (CCFF) method. In this mode, the circuit classically operates in Critical conduction Mode (CrM) when the inductor current exceeds a p.
necessary for robust and compact PFC stages, with few external components.
General Features
• Near-unity Power Factor
• Critical Conduction Mode (CrM)
• Current Controlled Frequency Fold-back (CCFF): Low Frequency
Operation is Forced at Low Current Levels
• On-time Modulation to Maintain a Proper Current Shaping in CCFF
Mode
• Skip Mode Near the Line Zero Crossing
• Fast Line/Load Transient Compensation
(Dynamic Response Enhancer)
• Valley Turn On
• High Drive Capability: −500 mA/+800 mA
• VCC Range: from 9.5 V to 35 V
• Low Start-up Consumption
• Six Versions: NCP1612A, B, A1, A2, A3 and B2 (.
