UCC28711 - Constant-Current Controller

This page provides the datasheet information for the UCC28711, a member of the UCC28710 Constant-Current Controller family.

Datasheet Summary

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.

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.
