Topology | Flyback Converter |
Input voltage | 90-275 V |
Output 1 | 5 V / 0.5 A |
IC revision | A |
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.
77% efficiency at 2.5W/5V/500mA
Remarks:L1=1mH And Transormer T1 Used
