25W Isolated Synchronous Flyback Reference Design

PMP10541

Design files

Overview

PMP10541 is an isolated synchronous flyback converter reference design which utilizes the LM5122 controller for industrial applications. The switching frequency is set to 230 kHz for high efficiency at a nominal output power of 25W. A planar power transformer provides good coupling and thermal performance. Secondary-side gate drive is coupled from the primary through a small isolation transformer.

Features
  • Synchronous rectification to improve efficiency
  • Isolated output
  • Wide input operation
  • Planar transformer
  • 4-layer board
