UCC28722 - Constant-Current Controller

Description

The UCC28722 flyback power supply controller provides isolated-output constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler.

Features

  • 1 < 50-mW No-Load Power.
  • Primary-Side Regulation (PSR) Eliminates Opto- Coupler.
  • Dynamic BJT Drive.
  • ± 5% Voltage and Current Regulation Across Line and Load.
  • 80-kHz Maximum Switching Frequency Enables High-Power Density Charger Designs.
  • Quasi-Resonant Valley-Switching Operation for Highest Overall Efficiency.
  • Wide VDD Range Allows Small Bias Capacitor.
  • Output Overvoltage, Low-Line, and Overcurrent Protection Functions.
