UCC28722 Product details

Description

The UCC28722 flyback power supply controller provides isolated-output constant-voltage (CV) and constant-current (CC) output regulation without the use of an optical coupler.

Features

1 < 50-mW No-Load Power.
Primary-Side Regulation (PSR) Eliminates Opto- Coupler.
Dynamic BJT Drive.
± 5% Voltage and Current Regulation Across Line and Load.
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.
Output Overvoltage, Low-Line, and Overcurrent Protection Functions.
