UCC28720 - Constant-Current Controller

General Description

The UCC28720 flyback power supply controller provides isolated-output Constant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an optical coupler.

Key Features

  • 1 < 10-mW No-Load Power.
  • Primary-Side Regulation (PSR) Eliminates Opto- Coupler.
  • ±5% Voltage and Current Regulation Across Line and Load.
  • 700-V Start-Up Switch.
  • 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.
  • Dynamic BJT Drive.
  • Overvoltage, Low-Line, and Overcurrent Pro.
