UCC2818 - BiCMOS Power Factor Pregulator

Download the UCC2818 datasheet PDF. This datasheet also covers the UCC2817 variant, as both devices belong to the same bicmos power factor pregulator family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCCx817 and UCCx818 family provides all the functions necessary for active power factor-corrected preregulators.

The controller achieves near-unity power factor by shaping the AC input line current waveform to correspond to that of the AC input line voltage.

Key Features

  • 1 Controls Boost Preregulator to Near-Unity Power Factor.
  • Limits Line Distortion.
  • World Wide Line Operation.
  • Over-Voltage Protection.
  • Accurate Power Limiting.
  • Average Current Mode Control.
  • Improved Noise Immunity.
  • Improved Feed-Forward Line Regulation.
  • Leading Edge Modulation.
  • 150-μA Typical Start-Up Current.
  • Low-Power BiCMOS Operation.
  • Up to 18-V Operation.
  • Frequency Range 6 kHz.
