TopologyPower Factor Correction
IC revision1

Description

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.

Features

  • High Voltage Start-Up Circuit
  • Critical conduction mode with current controlled frequency foldback
  • Integrated Input Filter Capacitor (X2) Discharge Circuitry
  • Dynamic Response Enhancer
  • Soft Overvoltage Protection
  • -500 mA/+800 mA Drive Capability
  • Two Vcc startup versions: 10.5 V (A & B) and 17 V (C & D)
  • AC Line Brownout Detection
  • PFC Okay Output

Typical applications

  • Off-line power supplies
  • Lighting Ballast / LED Lighting Drivers and Power Supplies
