Design files

Overview

This reference design is a dual-channel, bidirectional converter suitable for 12-V to 12-V, dual-battery system, automotive applications. This reference design has a wide input range (3 V to 40 V) and could give full load (1kW) in the input voltage from 9V to 18V by using two LM5170-Q1 controllers. The efficiency is up to 98% at Vin = 18V, Vout = 12V, Iout = 40A.

Features
  • Full load is up to 1-kW
  • A dual-channel, bidirectional converter
  • The efficiency is up to 98%
