UCC2817-EP - BiCMOS POWER-FACTOR PREREGULATOR

Datasheet Summary

Description

The UCC2817 and UCC2818 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.

Features

  • 1.
  • 2 Controls Boost Preregulator to Near-Unity Power Factor.
  • Limits Line Distortion.
  • World-Wide Line Operation.
  • Overvoltage 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.
  • 12-V to 17-V Operation.
