Beschreibung

The NCP1680 is a Critical Conduction Mode (CrM) Power Factor Correction (PFC) controller IC designed to drive the bridgeless Totem Pole PFC (TPFC) topology. The bridgeless totem pole PFC consists of two totem pole legs:a fast switching leg driven at the PWM switching frequency and a second leg that operates at the AC line frequency. Thistopology eliminates the diode bridge present at the input of a conventional PFC circuit, allowing significant improvement in efficiency and power density.

Eigenschaften

  • Totem Pole PFC Topology Eliminates Input Diode Bridge.
  • Critical Conduction Mode (CrM) Operation.
  • Discontinuous Conduction Mode (DCM) with Valley Turn On Under Light Load Condition.
  • Frequency Foldback in DCM With 25 kHz Minimum Frequency
  • Skip Mode in Very Light Load Condition
  • Proprietary Current Sense Scheme
  • Digital Voltage Loop Compensation
  • AC Line Monitoring Circuit & AC Phase Detection
  • Near Unity Power Factor in All Operating Modes
  • PFC OK Indicator
