Texas Instruments UCD3138064A | Demoboard PMP23332

Interleaved and multiphase inverting buck-boost converter reference design

Overview

TopologyFPGA
IC revisionA

Description

This reference design uses the UCD3138064A as a digital controller to control inverting buck-boost with the capability of supporting two-phase peak current mode control. The soft-switching technology is used in this design to improve the power efficiency. The input voltage range is -62 V to -36 V. The output voltage range is adjustable from 28 V to 52 V. The default output voltage is 48-V with a maximum current of 14 A.

Features

  • High efficiency above 97.1%
  • Interleaved two-phase peak current mode (PCM) control
  • Three phases with voltage mode (VM) control
  • Zero voltage switching of MOSFETs
  • Pre-biased start up
  • Current balancing between phases

Typical applications

  • Non-isolated battery backup unit
  • Transformer-based DC/DC converter (100W~400W)
