Part Number : UCC28910
Function : High-Voltage Flyback Switcher / Low Line and Output Over-Voltage Protection
Package : SOIC 7 Pin Type
Maker : Texas Instruments
Pinouts : 
Description :
The UCC28910 is dedicated to isolated flyback power supplies and provides output voltage and current regulation without the use of an optical coupler. The device incorporates a 700-V power FET and a controller that processes operating information from the auxiliary flyback winding and from the power FET to provide precise output voltage and current control.
Features
1. 700-V Start-Up and Smart Power Management Enables <30-mW Standby Power
2. 115-kHz Maximum Switching Frequency Design for High-Power Density
3. Valley Switching and Frequency Dithering to Ease EMI Compliance
4. Thermal Shut Down
5. Low Line and Output Over-Voltage Protection
