The NCP1615 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 NCP1615 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.
This product is IEC60950 compliant. Please see the test report and certification in the Conformance report section below.
Features   Benefits
     
  • High Voltage Start-Up Circuit
 
  • Improved efficiency at light load and fast startup time
  • Critical conduction mode with current controlled frequency foldback
 
  • Optimizes conversion efficiency across load range
  • Integrated Input Filter Capacitor (X2) Discharge Circuitry
 
  • Improved light load efficiency and elimination of external resistors
