Design files

Overview

The PMP20904 reference design is a negative buck utilizing the LM5117 controller for industrial applications. This design can operate at 24Vin at +/-10%. The design has an output of -24V and capable of sourcing 2A continuous current and up to 4A transient. Switching frequency is set to 200kHz, and a 4 layer PCB is used.

Features
  • Synchronous output rectification
  • Low BOM count and cost, compact solution size
  • Peak efficiency: 94%
