Texas Instruments UCC28880 | Demoboard PMP10175

Universal AC Input, 5V/500mA DC output, Non-isolated Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage90-275 V
Output 15 V / 0.5 A
IC revisionA

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
