PMP10175
通用 AC 輸入、5V/500mA DC 輸出、非隔離返馳式轉換器參考設計
PMP10175
概覽
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.
特點
- 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
