UCC28701 - Constant-Current Controller

Download the UCC28701 datasheet PDF. This datasheet also covers the UCC28700 variant, as both devices belong to the same constant-current controller family and are provided as variant models within a single manufacturer datasheet.

Description

The UCC28700 family of flyback power supply controllers provides Constant-Voltage (CV) and Constant-Current (CC) output regulation without the use of an optical coupler.

Features

  • 1 < 30-mW No-Load Power for 5-Star Rating.
  • Primary-Side Regulation (PSR) Eliminates Opto- Coupler.
  • ±5% Voltage and Current Regulation.
  • 130-kHz Maximum Switching Frequency Enables High-Power Density Charger Designs.
  • Quasi-Resonant Valley-Switching Operation for Highest Overall Efficiency.
  • Patent-Pending Frequency-Jitter Scheme to Ease EMI Compliance.
  • Wide VDD Range Allows Small Bias Capacitor.
  • Clamped Gate-Drive Output for MO.
