500-W interleaved SEPIC reference design

Overview

TopologyBuck Converter
Input voltage45-60 V
Output 110 V
IC revisionA

Description

This 500-W interleaved SEPIC converter reference design supplies a non-isolated adjustable 5 V to 110 V output voltage with a maximum output current of 5 A. The main power stage uses two LM5122 controllers to power the primary and secondary phases of the SEPIC. A LM5007 buck converter is used to generate a local 10 V bias.

Features

Interleaved power stages reduces output capacitance1-V peak-to-peak ripple at full load with output voltage of 110-VAchieves over 96% efficiency above 500-W loading across input voltage range

Typical applications

  • Non-Isolated DC/DC Buck Regulator
  • Secondary High-Voltage Post Regulator
  • 48-V Automotive Systems
