NCP1615GEVB: High Voltage PFC Controller with Current Controlled Frequency Foldback Evaluation Board

The NCP1615C is a high voltage PFC controller designed to drive PFC boost stages based on an innovative Current Controlled Frequency Foldback (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 NCP1615C linearly decays the frequency down to a minimum of about 26 kHz when the input current is zero. CCFF maximizes the efficiency at both nominal and light load. In particular, the standby losses are reduced to a minimum. An innovative circuitry allows near−unity power factor even when the switching frequency is reduced.The integrated high voltage startup circuit eliminates the need for external startup components and consumes negligible power during normal operation. Housed in a SOIC-16 package, the NCP1615C also incorporates the features necessary for robust and compact PFC stages, with few external components.
