Texas Instruments UCC27211DDA | Demoboard TIDA-010087
120-V Boot, 4-A Peak, High-Frequency High-Side and Low-Side Driver
Overview
| Topology | Buck Converter |
| Input voltage | 12-15 V |
| IC revision | E2 |
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
