STEVAL-ISA079V1 demonstration board is based on the DC-DC monolithic regulator L6928D, specifically designed to provide extremely high efficiency. The L6928D supply voltage can be as low as 2 V, allowing it to be used in single Li-Ion cell supplied applications.</p> <p>Output voltage can be selected by an external divider down to 0.6 V. Duty cycle can saturate to 100%, allowing low dropout operation. The previous part number for this demonstration board was EVAL6928D.</p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>2 V to 5.5 V battery input range</li> <li>High efficiency: up to 95%</li> <li>Extremely low quiescent current</li> <li>1 &mu;A max. shutdown supply current</li> <li>800 mA max. output current</li> <li>Adjustable output voltage from 0.6 V</li> <li>Low dropout operation: up to 100% duty cycle</li> <li>&plusmn; 1% output voltage accuracy</li> <li>1.4 MHz switching frequency externally synchronizable from 1 MHz to 2 MHz</li> <li>Short-circuit protection</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Evaluation 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">Data Sheet</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/web/en/resource/technical/document/datasheet/CD00047477.pdf" target="_blank">L6928 High efficiency monolithic synchronous step down regulator (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 xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/document/data_brief/DM00049876.pdf" target="_blank">DB1574: High efficiency monolithic synchronous step-down regulator based on the L6928D (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">Bill of Materials</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/bill_of_materials/steval-isa079v1_bom.pdf" target="_blank">STEVAL-ISA079V1 BOM (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment "> <i class="fal fa-file-archive"></i> <a href="http://www.st.com/st-web-ui/static/active/en/resource/technical/layouts_and_diagrams/board_manufacturing_specification/steval-isa079v1_gerber.zip" target="_blank">STEVAL-ISA079V1 gerber files (zip)</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/technical/layouts_and_diagrams/schematic_pack/steval-isa079v1_schematic.pdf" target="_blank">STEVAL-ISA079V1 schematics (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: step-down regulator, L6928D, power_management, stm, stepdown_buck_regulator, analog_demo_boards</div>
