Product Overview

The NCP1654BD65R2G is a Power Factor Controller for continuous conduction mode (CCM) power factor correction step-up pre-converters. It controls the power switch conduction time (PWM) in a fixed frequency mode and in dependence on the instantaneous coil current. The circuit minimizes the number of external components and drastically simplifies the PFC implementation. It also integrates high safety protection features that make the NCP1654 a driver for robust and compact PFC stages like an effective input power runaway clamping circuitry.
  • Average current continuous conduction mode
  • Fast transient response
  • Very few external components
  • Very low startup currents (<400A)
  • Low operating consumption
  • Latching PWM for cycle-by-cycle duty-cycle control
  • Internally trimmed internal reference
  • Undervoltage lockout with hysteresis
  • Soft-start for smoothly startup operation
  • Shutdown function
  • Pin to pin compatible with industry standard inrush currents detection
  • Overvoltage protection
  • Undervoltage detection for open loop detection or shutdown
  • Brown-out detection
  • Soft-start
  • Accurate overcurrent limitation
  • Overpower limitation
