Productomschrijving
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 minimum of about 26kHz at the sinusoidal zero-crossing. CCFF maximizes the efficiency at both nominal and light load. In particular, the standby losses are reduced to a minimum.
Improved efficiency at light load and fast startup time
Optimizes conversion efficiency across load range
Improved light load efficiency and elimination of external resistors
Improved transient response for line and load steps
Reduces acoustic noise and stress in the event of an overvoltage fault
Supports wide range of MOSFETs and power levels
Protects boost stage power components during line fault conditions
