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...
