Operating over an input voltage range of 38\u201360 V, the 4:1 input to output ratio results in an output range of 9.5\u201315 V.<\/p>\n\n\n\n<p>At an input voltage of 54 V, the efficiency of the module is as high as 97.5% at 50% load (31 A), and the part is thermally optimized for cold wall mounting via the attached baseplate. The BMR314 is offered in an industry standard LGA footprint and pin-out for security of supply and second-sourcing. The incredibly compact package can deliver a power density of more than 300 W\/cm<sup>3<\/sup> or 5.1 kW\/in<sup>3<\/sup> when delivering peak power to the load.<\/p>\n\n\n\n<p>Designed in particular for powering cloud based applications including AI, machine learning and hyperscale computing, the BMR314 also integrates a PMBus interface for ease of monitoring, configuration and control capabilities, and enables easy integration with the <a href=\"\/products\/power-modules\/flex-power-designer\" target=\"_blank\" rel=\"noreferrer noopener\">Flex Power Designer<\/a> design tool.<\/p>\n\n\n\t\t\t<\/div>\n\t\t\t<\/div>\n\t\n\t<script>\n\t(function () {\n\t\tlet hasRun_id_69d909bd3c459 = false;\n\t\tfunction updateVideoDisplay_id_69d909bd3c459() {\n\t\t\tconst youtubeVideoId = \"\";\n\t\t\tconst bynderID = \"\";\n\t\t\tconst mediaType = \"image\";\n\t\t\tconst mediaVideoElement = document.getElementById('media-video-id_69d909bd3c459');\n\t\t\tconst bodyClass = document.body.className || '';\n\t\t\tconst match = bodyClass.match(\/translatepress-([a-z]{2})(?:_[A-Z]{2})?\/i);\n\t\t\tconst currentLanguage = match ?
