UCC28701 - Constant-Current Controller

This page provides the datasheet information for the UCC28701, a member of the UCC28700 Constant-Current Controller family.

Datasheet Summary

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.
