Description
The UCC28720EVM-212 is a 5W evaluation module for evaluating an off line adapter for USB applications. It is intended for evaluation purposes and is not intended to be an end product. The UCC28720EVM-212 converters 100V to 240V RMS input voltage down to 5V DC, with a 1A current limit for USB adapter applications.
Features
Features<10mW no load powerPrimary Side Regulation (PSR) eliminates opto-coupler+/- 5% Voltage & Current RegulationQuasi-resonant valley switching operation for highest overall efficiencyWide VDD range (35V) allows small bias capacitorDrive Output for low cost BipolarProtection Functions: Over Voltage, Low Line, Over Current
Typical applications
- White Goods
- USB-Compliant Adapters and Chargers for 80 kHz and always maintains control of the peakConsumer Electronic
- Standby Supply for TV and Desktop
