Texas Instruments UCC28880 | Demoboard PMP10175

Description

This design demonstrates the use of UCC28880 high-voltage switcher to design an Offline Non-Isolated Flyback converter that can supply greater than 100mA output current. Using direct resistor-divider feedback, this design delivers a well-regulated 5V/500mA output with minimal component count.

Features

• UCC28880 based Non-Isolated Flyback converter
• Design delivers >100mA output current
• 5V output, regulated by direct resistor divider feedback network

• 77% efficiency at 2.5W/5V/500mA

• Tightly regulated 5V output (<1.5%, at 25C) using direct resistor divider feedback
• Short-circuit withstand capability of 3 seconds
• This design is tested and includes test results and CAD files

Remarks:L1=1mH And Transormer T1 Used
