platform for evaluation of the L5973AD, a step-down monolithic power switching regulator capable of delivering up to 1.5 A of current at output voltages from 1.2 V to 35 V. The input supply voltage of the STEVAL-ISA106V1 can range from 4 V to 36 V based on the rated voltage of the input capacitor, while the output voltage is adjustable from 1.235 V to VCC.</p> <p>The L5973AD is a step down monolithic power switching regulator with a switch current limit of 2A so it is able to deliver more than 1.5 A DC current to the load depending on the application conditions. The output voltage can be set from 1.235 V to 35 V. The high current level is also achieved thanks to an SO8 package with exposed frame, that allows to reduce the R<sub>thJA</sub> down to approximately 40 &deg;C/W.</p> <p><strong>Applications:</strong></p> <ul> <li>Consumer: STB, DVD, TV, VCR, car radio, LCD monitors</li> <li>Networking: XDSL, modems, DC-DC modules</li> <li>Computer: printers, audio/graphic cards, optical storage, hard disk drive</li> <li>Industrial: chargers, car battery, DC-DC converters</li> </ul> <p></p> </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>Max. output current Iout = 1.5 A</li> <li>Output voltages from 1.235 V to 35 V</li> <li>Operating input voltage ranges from 4 V to 36 V</li> <li>Internal switching frequency: 500 kHz</li> <li>Synchronization pin</li> <li>Short-circuit protection</li> <li>Inhibit pin</li> <li>Thermal shutdown</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/st-web-ui/static/active/en/resource/technical/document/datasheet/CD00003370.pdf" target="_blank">DS3330: 2 A switch step down switching 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/DM00061731.pdf" target="_blank">DB1716: 1.5 A step-down switching regulator based on the L5973AD (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-isa106v1_bom.pdf" target="_blank">STEVAL-ISA106V1 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-isa106v1_gerber.zip" target="_blank">STEVAL-ISA106V1 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-isa106v1_schematic.pdf" target="_blank">STEVAL-ISA106V1 schematics (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: Step-down Switching Regulator, power_management, stm, stepdown_buck_regulator, L5973AD, analog_demo_boards</div>
