NCP1611ADR2G Integrated Circuit Chip Power Factor Correction 550mW Power Factor Controller

NCP1611ADR2G Integrated Circuit Chip Power Factor Correction 550mW Power Factor Controller​

Product Description Of NCP1611ADR2G

NCP1611ADR2G is Enhanced, High-Efficiency Power Factor Conduction, it 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 NCP1611ADR2G linearly decays the frequency down to about 20 kHz when the current is null.
