PMP20708

Design files

Overview

The PMP20708 reference design uses UCC28881 low cost MOSFET integrated controller to provide 24V/30mA and 5V/30mA dual-output from an ultra-wide 24V to 264V (AC or DC) input. The board is in a small form factor of 30mm x 41mm x 12mm with minimized populated parts.

Features
  • 24V to 265V input (AC or DC)
  • Board dimension: 30mm x 41mm x 12mm
  • 24V/30mA and 5V/30mA dual outputs
  • Test report included
