Design files

Overview

The PMP11405 reference design uses the UCC28740 constant current (CC), constant voltage (CV) flyback controller for a 5V/1A, 12V/0.9A bias supply with high line AC input (185VAC to 260VAC input). With safety isolated, Over 80% efficiency is achieved at full load and less than 400mW power consumption is observed during no load condition.

Features
  • High line AC input to 5V/1A and 12V/0.9A dual-output
  • 1.45" x 4.45" board dimension
  • CC & CV is enabled with UCC28740 flyback controller
  • Less than 400mW no load power consumption
  • Cross regulation tested
