Design files

Overview

PMP11281 is a quasi-resonant Flyback power suppy based on the UCC28730 primary side regulation (PSR) controller. The elimination of optocoupler using PSR topology promises higher reliability and lower system cost. The design achieves less than 40mW standby power losses and over 88% average efficiency. The design also features UCC2463x synchronous rectification controller.

Features
  • 85VAC to 265VAC, 50/60Hz input, 5V/10A/50W output
  • Over 88% average 4-point efficiency
  • Over 77% efficiency at 10% load (5W)
  • Less than 40mW standby power losses
  • Protected against output short-circuits
