NCP1611 High-Efficiency Power Factor Controller

NCP1611 Enhanced, High-Efficiency Power Factor Controller The NCP1611 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 www.onsemi.com programmable value. When the current is below this preset level, the NCP1611 linearly decays the frequency down to about 20 kHz when MARKING the current is null. CCFF.
