Description
The UCC28720 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 < 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.
- 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.
- Dynamic BJT Drive.
- Overvoltage, Low-Line, and Overcurrent
Pro.
