The power supply block uses the ST78L33 linear regulator to provide the 3.3 V logic supply for the microcontroller.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <p></p> <ul> <li>Input voltage range: 7 to 42 V_dc</li> <li>Output current: 2 A (5 A peak)</li> <li>Can operate up to 100% duty cycle</li> </ul> <p></p> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Board</li> </ul> <div id="devtool-required-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Required Tools</h3> <div id="devtool-required-devtools-content"></div> </div> <div id="devtool-accessory-devtools-section" class="xs-hide"> <h3 class="toc-item xs-pb2 xs-mb1 xs-border-bottom">Accessory Tools</h3> <div id="devtool-accessory-devtools-content"></div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Documents</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Application Note</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/application_note/DM00072008.pdf" target="_blank">AN4220: Sensorless six-step BLDC commutation (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">License Agreement</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/legal/legal_agreement/license_agreement/EvaluationProductLicenseAgreement.pdf" target="_blank">Evaluation products license agreement (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Product Brief/Fact sheet</h4> <div class="attachment "> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/data_brief/DM00073153.pdf" target="_blank">DB1860: 6-step BLDC sensorless driver board based on the STM32F051 and L6234 (pdf)</a> </div> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/sales_and_marketing/promotional_material/brochure/brfactory_web.pdf" target="_blank">Products and Solutions for Factory Automation and Control (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">User Manual/Guide</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/CD00298474.pdf" target="_blank">UM1052: STM32F PMSM single/dual FOC SDK v4.2 (pdf)</a> </div> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Downloads</h3> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Applications Library</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="http://www.st.com/st-web-ui/static/active/en/st_prod_software_internet/resource/technical/software/sw_development_suite/stsw-stm32100.zip" target="_blank">STM32 PMSM FOC Software Development Kit -
