Description

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. The device processes
information from the primary power switch and an auxiliary flyback winding for precise control of output voltage and current.
Features
• < 50-mW No-Load Power
• Primary-Side Regulation (PSR) Eliminates OptoCoupler
• 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
• Programmable Cable Compensation
• SOT23-6 Package
Applications
• USB-Compliant Adapters and Chargers for Consumer Electronics
– Smart Phones
– Tablet Computers
– Cameras
• Standby Supply for TVs and Desktops
• White Goods
