Description

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
