PMP10491

Design files

Overview

The wide 9-36Vdc input range of this design is well suited for applications operating from 12V/24V dc inputs.  The synchronous rectifier provides excellent efficiency over the full input range.

Features
  • Excellent efficiency (89% at 3A)
  • 1500VRMS isolation
  • Small size (32 x 35mm)
  • 8.4mm max transformer height
