Description

The PMP10467 reference design uses the UCC28911 primary-side regulated flyback controller with integrated MOSFET to generate a 5V/1.4A output from an univeral AC input with safety isolation rated transformer on a single layer board. About 50degC temperature rise on UCC28911 is observed at full load. It is notable that the power consumption at no load is less than 40mW.

Features
  • Universal AC input with 5V/1.4A output
  • Less than 40mW no load power consumption
  • MOSFET integrated PSR controller on a single layer board
  • About 50oC temperature rise on the controller at full load
  • Test report is available
