TopologyBuck Converter
Input voltage4.5-37 V
IC revisionE2

Description

This reference design illustrates a method to precisely control the current and voltage of a bidirectional interleaved buck-converter power stage using a C2000™ microcontroller (MCU) and a precision ADC ADS131M08. This design achieves less than ±20-mA current regulation error, and ±1-mV voltage regulation error by utilizing a high-resolution pulse-width modulation (PWM) generation peripheral of the C2000 MCU.FeaturesDual-phase interleaved 600-W bidirectional buck power stage15.8-bits PWM resolution at 100-kHz switching frequencyExternal delta-sigma ADC for closed-loop controlConstant current charging and discharging with regulation error < ±20 mAConstant voltage mode supported in both charging and discharging with regulation error < ±1 mV

Typical applications

  • 100-A Dual-phase digital control battery tester reference design
