Design files

Overview

The PMP4320A reference design is a single output DC-DC converter with standard half-brick dimensions and full digital control configuration based on the UCD3138.  It is capable of delivering 50A output current with an output voltage of 12V.  The converter provides high efficiency and good performance with flexible configuration options, which makes it an ideal choice for the bus converter.

Features
  • Fully tested to comply with telecom customer requirements
  • Flexible configuration of key parameters
  • Full Bridge converter with synchronous rectifier
  • Good thermal performance with low component count
  • Efficiency of 93.9%
  • Protection features output OVP, OCP and input UVP

A fully assembled board has been developed for testing and performance validation only, and is not available for sale.
