Rows are multiplexed by 5 internal PMOS transistors.Current mirrors are supplied by the integrated boost converter. Its output voltage is adjustable so it Can be adapted to the forward voltage of LEDs. It reduces power dissipation and improves efficiency.</p><p> </p><p >STLED524 Chinese data sheet: Click to download</p><p >More schematics And source code popular application circuit: Click now</p> </div> </div> <div class="tech-detail-share"> <!-- Baidu Button BEGIN --> <div class="bdsharebuttonbox" > <a href="#" class="bds_qzone" data-cmd="qzone" title="Share to QQ Space"></a> <a href="#" class="bds_tsina" data-cmd=" Tsina" title="分Go to Sina Weibo"></a> <a href="#" class="bds_weixin" data-cmd="weixin" title="Share to WeChat"></a> <span>Share to:</span > </div> <script>window._bd_share_config = { "common": { "bdSnsKey": {}, "bdText": "", "bdMini": "1", "bdMiniList": false, "bdPic": "", "bdStyle": "2", "bdSize": "16" }, "share": {} }; with (document) 0[(getElementsByTagName(
