Overview

TopologyOther Topology
Input voltage8-16 V
Output 15 V
IC revisionA

Description

This reference design provides a multi-phase solution for a wide range of current battery test applications. Leveraging the dual phase buck/boost controller LM5170's daisy chain configuration gives the design the ability to achieve 100A charging/discharging rates. Utilizing high accuracy constant current (CC) and constant voltage (CV) calibration loops, TIDA-01041 can achieve up to 0.01% voltage control accuracy. All key design theories are described guiding users through the part selection process and optimization. Finally, schematic, board layout, hardware testing, and results are also presented.

Features

  • High precision calibration control achieving 0.02% full scale current control accuracy and 0.01% full scale voltage control accuracy
  • Supports from 0.5-A to 100-A charge and discharge
  • Input voltage (bus) from 8 V–16 V and output load (battery) from 0 V–4.2 V (5 V max)
  • Two LM5170 multiphase bidirectional buck, boost integrated controllers and drivers for charging and discharging

Typical applications

  • Battery test equipment
