← Back to Reference Designs Overview

Target Applications

• Battery formation & test
• Programmable DC power supply

Features & Specification

• Bidirectional current control up to 10 A with less than ±0.01% accuracy
• Four channels independent current and voltage control
• External delta-sigma ADC for closed loop control
• Constant current charging and discharging with regulation error less than ± 1mA
• Constant voltage charging and discharging with regulation error less than ± 0.5mV

Description

This reference design provides a cost-effective solution for battery formation and test applications.

This design leverages the C2000™ TMS320F280039C real-time MCU for high-resolution pulse-width modulation (PWM) generation, and constant-current (CC) and constant-voltage (CV) control loops. It efficiently utilizes the MCU, and does not require a precision digital-to-analog converter, which saves more than 30% in the bill of materials. The flexibility of current and voltage loops in software allows users to achieve multiple current and voltage levels output with one design.
