Design files

Overview

The PMP10937 reference design uses Buck converter to convert universal AC input voltage  to a 18V/0.3A DC output with UCC28700 controller. Circuit simplicity is achieved with quasi-resonant valley-switching operation and the utilization of Buck topology. With all components placed within the dimension of 1.05" x 2.1", over 80% efficiency is achieved at full load and no load power consumption of this board is about 150mW.

Features
  • Universal AC input with 18V/0.3A output
  • About 150mW no load power consumption
  • Over 80% efficiency is achieved at full load
  • Less than 40degC temperature rise
  • 1.05" x 2.1" X-Y dimension
  • Test report is available
