Correction Controller
The NCP1616 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
operates in critical conduction mode (CrM) when the inductor current
exceeds a programmable value. When the current is below this preset
level, the NCP1616 linearly decays the frequency down to a minimum
of about 26 kHz at the sinusoidal zerocrossing. CCFF maximizes the
efficiency at both nominal and light load. In particular, the standby
losses are reduced to a minimum. 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 SOIC9 package, the NCP1616
incorporates the features necessary for robust and compact PFC
stages, with few external components.
