2460-W bidirectional boost converter reference design for automotive applications

Overview

TopologyBoost Converter
Input voltage12 V
Output 148 V / 51.25 A
IC revisionB

Description

This reference design is a 2460-W bidirectional boost converter for automotive applications. The circuit is powered from the nominal 12-V battery to provide an output voltage of 48 V at 51.25 A. The design uses two dual-phase synchronous bidirectional controllers operating at a switching frequency of 200 kHz per phase. The 48-V output is designed to drive a motor. When the load current reverses and the output voltage reaches 54 V, hysteretic direction control allows the load current to be returned to the 12-V battery. Normal boost operation resumes when the output voltage returns to 48 V. Mounting holes are provided for a bottom-side heat sink underneath the MOSFETs.

Features

  • Bidirectional boost solution for higher power
  • Excellent phase current sharing for balanced thermal performance
  • Jumper selectable phase control
  • Mounting option for bottom-side heat sink
  • Reverse battery protection

Typical applications

  • DC-DC Power Supplies for Industrial, Communications, and Automotive Applications
  • Boost, Flyback, SEPIC and Forward Converter Topologies
