Designers have reduced power rail voltages to minimize the resulting extra dissipation, but this complicates the power distribution network (PDN) design. As a result, common schemes are to do power conversion in steps with \u2018intermediate bus converters\u2019 (IBCs) followed by \u2018point of load\u2019 converters (PoLs) or Voltage Regulator Modules (VRMs) to minimize losses. The PoL\/VRM is placed as close to the end load as possible on the same lateral plane, but at the highest currents the connection distance when located alongside the load still produces voltage drops along tracks, both from resistance and inherent inductance, compromising performance.<\/p>\n\n\n\n<p>A solution is to instead put the PoL\/VRM directly underneath the chip for the closest possible connection, and this is an approach enabled by the latest customized products and design capabilities from Flex Power Modules. Termed \u2018Vertical Power Delivery\u2019 modules, the DC\/DC converters have pinouts customized to directly match the processor pinout with up to 2400 solder balls, and are low profile to enable bottom-side mounting. The placement of the conversion stage directly under the load minimizes the distance that the high currents need to travel, hence significantly reducing the PDN resistances and losses, helping both system efficiency and load transient response.<\/p>\n\n\n\n<p>This recent example of a custom device developed for a key customer is rated to 670 A continuous\/1300 A peak and operates over an input range of 5-7.5 V with an output programmable from 0.6-0.9 V and an efficiency rating of 86%. An external controller assembly is needed, which was also developed by Flex Power Modules, which can handle sixteen parallel phases and includes monitoring and alarm functions. Physically, this example is 22 x 43 x 6 mm and includes 800 solder balls for its BGA connections. Heat generated is removed by a cold plate, typically liquid cooled, on the \u2018top side\u2019 of the module where the power semiconductors are mounted with co-planar surfaces.<\/p>\n\n\n<div class=\"spacer block\" style=\"height: 24px;\">\n\t<\/div>\n\n\n<p class=\"link-arrow\"><a href=\"\/products\/power-modules\/vertical-power-delivery\" data-type=\"page\" data-id=\"34001\">Learn more about Vertical Power Delivery<\/a><\/p>\n\n\n\t\t<\/div>\n\t\t<div class=\"sidebar normal-column\">\n\t\t\t\t\t\t\t\t\t<div class=\"post\">\n\t\t\t\t\t\t\t\t<a title=\"Powering data centers from grid to chip\" class=\"image\" href=\"https:\/\/flex.com\/downloads\/powering-data-centers-from-grid-to-chip\" target=\"_self\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"Powering data centers from grid to chip\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2026\/02\/2024-Power-Brochure_DIGITAL-cover-540x304.jpg\" title=\"\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"label\">\n\t\t\t\t\t\t\tBrochure\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t<a title=\"Powering data centers from grid to chip\" class=\"title\" href=\"https:\/\/flex.com\/downloads\/powering-data-centers-from-grid-to-chip\" target=\"_self\">\n\t\t\t\t\tPowering data centers from grid to chip\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\t\t\t<div class=\"post\">\n\t\t\t\t\t\t\t\t<a title=\"IBC\u00a0conversion\u00a0ratios:\u00a0how to choose between 4:1 and 8:1\" class=\"image\" href=\"https:\/\/flex.com\/zh\/resources\/ibc-conversion-ratios-how-to-choose-between-41-and-81\" target=\"_self\">\n\t\t\t\t\t\t\t\t\t\t<img decoding=\"async\" alt=\"IBC conversion ratios: how to choose between 4:1 and 8:1\" src=\"https:\/\/flex.com\/wp-content\/uploads\/2026\/03\/Power-Modules-_-4.1-vs-8-540x304.jpg\" title=\"\">\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t\t<div class=\"label\">\n\t\t\t\t\t\t\tBlog\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<\/a>\n\t\t\t\t<a title=\"IBC\u00a0conversion\u00a0ratios:\u00a0how to choose between 4:1 and 8:1\" class=\"title\" href=\"https:\/\/flex.com\/zh\/resources\/ibc-conversion-ratios-how-to-choose-between-41-and-81\" target=\"_self\">\n\t\t\t\t\tIBC\u00a0conversion\u00a0ratios:\u00a0how to choose between 4:1 and 8:1\t\t\t\t<\/a>\n\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t<\/div>\n<\/div>\n\n<div class=\"spacer block\" style=\"height: 72px;\">\n\t<\/div>","protected":false},"excerpt":{"rendered":"<p>Introducing Vertical Power Modules, power conversion modules that help solve for the increase in modern data processing.<\/p>","protected":false},"author":3,"featured_media":20893,"template":"","categories":[43,90,97],"tags":[],"content-type":[13],"class_list":["post-20886","resource","type-resource","status-publish","has-post-thumbnail","hentry","category-power","category-data-center-power","category-power-modules","content-type-blog"],"acf":[],"_links":{"self":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20886","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":4,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20886\/revisions"}],"predecessor-version":[{"id":40876,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/resource\/20886\/revisions\/40876"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/media\/20893"}],"wp:attachment":[{"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/media?parent=20886"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/categories?post=20886"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/tags?post=20886"},{"taxonomy":"content-type","embeddable":true,"href":"https:\/\/flex.com\/zh\/wp-json\/wp\/v2\/content-type?post=20886"}],"curies":[{"name":"\u53ef\u6e7f\u6027\u7c89\u5242","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
