Now</a> </div> </div> </div> </div> <div class="xs-mt3"> The STEVAL-LLL003V1 evaluation board is a constant current LED driver, based on non-isolated buck topology using VIPer0P. The board delivers 130 mA &plusmn; 2.5% at an output load of 15 - 21 white LEDs. The buck topology ensures a minimum number of components as well as higher efficiency when operating at high output voltage (60 V and above). The application core is the new VIPer0P offline high voltage converter which smartly integrates an 800 V avalanche rugged power MOSFET with current-mode control. Thanks to the embedded E/A (EAGND) floating GND, the direct current regulation can be applied to the buck converter, improving the LED current accuracy. </div> <h3 class="toc-item xs-pb2 xs-border-bottom">Features</h3> <ul> <li>Non-isolated buck topology</li> <li>Two input voltage ranges: <ul> <li>US range: 85-135 VAC (jumper J2 - closed, voltage doubler)</li> <li>EU range: 175-285 VAC (jumper J2 - open, bridge rectifier)</li> </ul> </li> <li>130 mA &plusmn;2.5% output constant current (15-21 white LEDs connected)</li> <li>60 kHz fixed frequency operation</li> <li>&cong;89% efficiency at maximum load</li> <li>Protections: <ul> <li>open/no-load circuit protection</li> <li>short/overload circuit protection</li> <li>thermal shutdown</li> </ul> </li> <li>Soft start for improved system reliability</li> <li>Meets IEC55022 Class B conducted EMI even with reduced EMI filter, thanks to the frequency jittering feature</li> <li>Meets IEC61000-4-2(ESD), IEC61000-4-4 (Burst) and IEC61000-4-5 (Surge)</li> <li>RoHS compliant</li> </ul> <h3 class="toc-item xs-pb2 xs-border-bottom">Ships With</h3> <ul> <li>Evaluation Board VIPER0P</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="https://www.st.com/resource/en/application_note/dm00447032.pdf" target="_blank">7.5 W non-isolated buck topology, constant-current LED driver based on VIPer0P (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="https://www.st.com/resource/en/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="https://www.st.com/resource/en/data_brief/steval-lll003v1.pdf" target="_blank">7.5 W non-isolated constant current LED driver based on VIPer0P (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="https://www.st.com/resource/en/bill_of_materials/steval-lll003v1_bom.pdf" target="_blank">STEVAL-LLL003V1 BOM (pdf)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Design Package</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-archive"></i> <a href="https://www.st.com/resource/en/board_manufacturing_specification/steval-lll003v1_gerber.zip" target="_blank">STEVAL-LLL003V1 gerber files (zip)</a> </div> </div> <div class="xs-px2"> <h4 class="xs-pb2 xs-border-bottom">Schematics/Layout Files</h4> <div class="attachment xs-mb3"> <i class="fal fa-file-pdf"></i> <a href="https://www.st.com/resource/en/schematic_pack/steval-lll003v1_schematic.pdf" target="_blank">STEVAL-LLL003V1 schematics (pdf)</a> </div> </div> </div> <div style="clear:both;"></div> <div style="font-size: 90%;">Tags: LED driver, buck converter, VIPer0P, stm, power management, analog_demo_boards</div>
