Design files

Overview

The PMP10767 reference design uses Buck converter to convert universal AC input voltage  to a 15V/0.13A DC output with UCC28911 controller. Circuit simplicity is achieved with quasi-resonant valley-switching operation and the utilization of Buck topology. Peak 77% efficiency is achieved at full load and no load power consumption of this board is less than 70mW.

Features
  • Universal AC input with 15V/0.13A output
  • Less than 70mW no load power consumption
  • MOSFET integrated PSR controller applied on Buck topology
  • About 20oC temperature rise on the controller at full load
  • Test report is available
