This puts strains on the power delivery network, particularly the \u2018Point of Load\u2018 DC\/DC converters or \u2018Voltage Regulator Modules\u2019 (VRMs) that see high currents in the tightest of spaces. In response, VRMs have been developed to be highly efficient and closely integrated with the end load, and one approach is to make the VRM power stage a separate module, with its user-chosen controller placed elsewhere.<\/p>\n\n\n\n<p>These \u2018integrated power stages\u2019 use space very efficiently and achieve staggering power density, around 150 W\/cm<sup>3<\/sup>&nbsp;or higher from packages with a footprint of less than 1 cm square. However, even though efficiencies of well over 90% are achieved, that does still mean 10 W or so of power to be dissipated and led away from the module.<\/p>\n\n\n<div id=\"id-69d8f3b576cd5\" class=\"columns block\">\n\t<style>\n\t\t#id-69d8f3b576cd5 .column, #id-69d8f3b576cd5 .wp-block-acf-column {\n\t\t\tpadding: 0 18px;\n\t\t}\n\t\t\n\t\t#id-69d8f3b576cd5 > .container.show-rules .column+.column, #id-69d8f3b576cd5 > .container.show-rules .wp-block-acf-column+.wp-block-acf-column {\n\t\t\tborder-color: rgba(38, 38, 38, 0.2);\n\t\t}\n\t\t\n\t\t#id-69d8f3b576cd5 .column, #id-69d8f3b576cd5 .wp-block-acf-column {\n\t\t\t.code.block {\n\t\t\t\t.container {\n\t\t\t\t\t.tagembed-widget {\n\t\t\t\t\t\tmax-width: 600px;\n\t\t\t\t\t}\n\t\t\t\t}\n\t\t\t}\n\t\t}\n\t\t\n\t\t@media (max-width: 1320px) {\n\t\t\t#id-69d8f3b576cd5 > .container {\n\t\t\t\tdisplay: block;\n\t\t\t\tmax-width: 600px;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 1320px) {\n\t\t\t#id-69d8f3b576cd5 > .container > .column, #id-69d8f3b576cd5 > .container > .wp-block-acf-column {\n\t\t\t\tpadding: 36px 0 0 0 !important;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 1320px) {\n\t\t\t#id-69d8f3b576cd5 > .container > .column:first-child, #id-69d8f3b576cd5 > .container > .wp-block-acf-column:first-child {\n\t\t\t\tpadding: 0 !important;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 1320px) {\n\t\t\t#id-69d8f3b576cd5 > .container.show-rules .column+.column, #id-69d8f3b576cd5 > .container.show-rules .wp-block-acf-column+.wp-block-acf-column {\n\t\t\t\tborder-left: none;\n\t\t\t\tborder-top: 1px solid rgba(38, 38, 38, 0.2);\n\t\t\t\tpadding: 30px 0 0 0 !important;\n\t\t\t\tmargin-top: 30px;\n\t\t\t}\n\t\t}\n\t<\/style>\n\t<div class=\"container align-center\">\n\t\t\n<div class=\"column block\">\n\t\n<div id=\"id-69d8f3b574c58\" class=\"box block content-width dark-content zh \" style=\"background-color: transparent; background-image: none;\">\n\t<style>\n\t\t#id-69d8f3b574c58 > .container > .content {\n\t\t\tbackground-color: transparent;\n\t\t\tposition: relative;\n\t\t\tpadding-top: 0px;\n\t\t\tpadding-right: 0px;\n\t\t\tpadding-bottom: 0px;\n\t\t\tpadding-left: 0px;\n\t\t\tmargin-left: 12px;\n\t\t\tmargin-right: 12px;\n\t\t}\n\t\t@media (max-width: 1272px) {\n\t\t\t#id-69d8f3b574c58.box.block.full-width > .container > .content {\n\t\t\t\tpadding-left: 0 !important;\n\t\t\t\tpadding-right: 0 !important;\n\t\t\t\tmargin: 0 !important;\n\t\t\t}\n\t\t}\n\t\t@media (max-width: 960px) {\n\t\t\t#id-69d8f3b574c58 > .container > .content {\n\t\t\t\t\/\/padding-top: 0px;\n\t\t\t\tpadding-right: 0px;\n\t\t\t\t\/\/padding-bottom: 0px;\n\t\t\t\tpadding-left: 0px;\n\t\t\t}\n\t\t}\n\t<\/style>\n\t<div class=\"container\">\n\t\t<div class=\"content\">\n\t\t\t\n<div id=\"id_69d8f3b56f1c5\" class=\"media block\">\n\t<div class=\"container media-center \">\n\t\t<div class=\"media\" style=\"left: 0px; min-width: 100%; max-width: 100%;\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"image none\">\n\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"BMR510 and BMR511\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2025\/09\/both-e1762361367669.png\" title=\"\">\n\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t<\/div>\n\t\n\t<script>\n\t(function () {\n\t\tlet hasRun_id_69d8f3b56f1c5 = false;\n\t\tfunction updateVideoDisplay_id_69d8f3b56f1c5() {\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_69d8f3b56f1c5');\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 ?

As the thermal resistance to the host board is relatively high, the BMR511 is commonly specified with some airflow and can achieve its full 80 A output to over 80\u00b0C ambient at 4 m\/s flow rate,<strong>&nbsp;Figure 3<\/strong>.<\/p>\n\n\n\n<p>If a cold plate is used, the full 80 A output can be obtained at 12&nbsp;V input up to 90\u00b0C host board and cold-plate temperature. This is with a 1 mm gap pad, thermal conductivity 8 W\/m.K. The application for the BMR511 bottom-cooled approach is when there is little or no space above the module, forced air is available and when the host board is designed to dissipate power through its surfaces.<\/p>\n\n\n<\/div>\n\n\t<\/div>\n<\/div>\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\" id=\"h-verifying-the-performance\" style=\"font-style:normal;font-weight:600\">Verifying the performance<\/h2>\n\n\n\n<p>All applications are different in their mechanical arrangement, airflow and thermal resistances to their ultimate sink for thermal energy, so Flex Power Modules defines their module thermal performance comprehensively. This means tests with defined module orientation, airflow rate, and temperature, along with defined host board and cold plate dimensions and their thermal resistances. In the product data sheets, critical points are identified with their maximum allowed temperatures. Over-temperature protection is nonetheless included, and temperature can be reported for remote monitoring. As an additional aid, thermal models for both products are available from Flex Power Modules on request.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-medium-font-size\" id=\"h-conclusion\" style=\"font-style:normal;font-weight:600\">Conclusion<\/h2>\n\n\n\n<p>Space above a host board determines whether top-cooling with a heatsink or cold-plate is viable and if so, concerns about the host board\u2019s ability to dissipate heat are not so much of an issue. If bottom-cooling is chosen, for space reasons or to save cost of heat sinking and its fixings, the host board must be designed and evaluated for its heat dissipation ability, and controlled airflow will normally be necessary. In either case, integrated power stages from Flex Power Modules perform well with their full rated output available.<\/p>\n\n\n\t\t<\/div>\n\t<\/div>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>\u6709\u6548\u6563\u70ed\u4ecd\u7136\u662f\u8bbe\u8ba1\u4e0a\u7684\u4e00\u5927\u6311\u6218\u3002\u672c\u6587\u5c06\u63a2\u8ba8Flex\u7535\u6e90\u6a21\u5757\u7684\u4e00\u4e9b\u6563\u70ed\u65b9\u6848\u3002.<\/p>","protected":false},"author":3,"featured_media":20882,"template":"","categories":[90,43,97],"tags":[],"content-type":[13],"class_list":["post-20880","resource","type-resource","status-publish","has-post-thumbnail","hentry","category-data-center-power","category-power","category-power-modules","content-type-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20880","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource"}],"about":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/types\/resource"}],"author":[{"embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/users\/3"}],"version-history":[{"count":9,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20880\/revisions"}],"predecessor-version":[{"id":40878,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20880\/revisions\/40878"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/media\/20882"}],"wp:attachment":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/media?parent=20880"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/categories?post=20880"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/tags?post=20880"},{"taxonomy":"content-type","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/content-type?post=20880"}],"curies":[{"name":"\u53ef\u6e7f\u6027\u7c89\u5242","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
