UCC28711 - Constant-Current Controller

Download the UCC28711 datasheet PDF. This datasheet also covers the UCC28710 variant, as both devices belong to the same constant-current controller family and are provided as variant models within a single manufacturer datasheet.

General Description

The UCC2871x family of flyback power supply controllers 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.
  • 100-kHz Maximum Switching Frequency Enables High-Power Density Charger Designs.
  • Resonant Valley-Switching Operation for Highest Overall Efficiency.
  • Frequency Jitter to Ease EMI Compliance.
  • Wide VDD Range Allows Small Bias Capacitor.
  • Clamped Gate-Drive Output.
