DATA SHEET www.onsemi.com Enhanced, High‐Efficiency Power Factor Controller NCP1612A, NCP1612B, NCP1612A1, NCP1612A2, NCP1612A3, NCP1612B2 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 programmable value.

When the current is below this preset level, the NCP1612 linearly decays the frequency down to a
