High Efficiency 180W AC/DC Power Supply Reference Design

PMP20694

Design files

Overview

PMP20694 is high-efficiency AC/DC power supply reference design with 85VAC-300VAC input and 36V/5A output. Transition mode PFC is applied with UCC28051 to prove high power factor and boost input voltage to 450VDC.  LLC resonant converter with UCC25600 is applied to step down the 450V to 36V output.  This design has over 92% peak efficiency. 

Features
  • 85VAC to 300VAC, 50/60Hz input to 36V/5A output
  • 68mm x 180mm board dimension
  • Test report available
  • 92% peak converter efficiency
