Description

The PMP10143 reference design demonstrates the use of UCC28880 high-voltage switcher to design an Offline Isolated Flyback converter that can supply greater than 100mA output current. Using 2ndary side feedback control, the design delivers a tighly regulated 3.3V/400mA output that can be used to bias micontrollers and DSPs. In addition the design also provides a 2nd output rail of 12V/30mA that can be used to supply relays and other analog devices.

Features
  • UCC28880-based Isolated Flyback converter
  • Design delivers >100mA output
  • Tightly regulated 3.3V output (<1%, at 25C) using 2ndary side opto-feedback
  • >74% efficiency at full-load on both rails
  • Flyback transformer designed for basic isolation
  • Short-circuit withstand capability of 3 seconds
  • This design is tested and includes test results and CAD files
