It is available in both a SIP (Single Inline Package) configuration, and a horizontal mount package.<\/p>\n\n\n\n<p>Delivering up to 40 A at output voltages from 0.6 V to 1.8 V, 30 A from 1.8 V to 3.3 V, and 20 A from 3.3 V to 5 V (100 W max), the total output voltage adjust range is from 0.6 V to 5 V, and the input voltage range is from 6 V to 15 V. This wide input range makes it suitable to be fed by fixed ratio intermediate bus converters which can deliver up to 15 V when being fed by a 60 V supply (4:1 ratio).<\/p>\n\n\n\n<p>Excellent thermal design, efficiency levels up to 96.1% (12V<sub>in <\/sub>\/ 5V<sub>out <\/sub>\/ 100% load), and a custom inductor design enables full load operation even with an 85\u00b0C ambient temperature with a 2.5 V output and only natural convection cooling. Higher ambient temperature operation is possible with suitable derating and cooling.<\/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_69d909aa0ae19 = false;\n\t\tfunction updateVideoDisplay_id_69d909aa0ae19() {\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_69d909aa0ae19');\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 ? match[1].toLowerCase() : 'en';\n\t\t\tconst isChineseLang = currentLanguage === 'zh';\n\t\t\tconsole.log('isChineseLang:', isChineseLang);\n\t\t\tconsole.log('Language detected:', currentLanguage);\n\t\t\tconst isValidYouTube = youtubeVideoId && \/^[A-Za-z0-9_-]{11}$\/.test(youtubeVideoId);\n\t\t\t\n\t\t\tif (!mediaVideoElement || mediaType !== \"video\") return;\n\t\t\tmediaVideoElement.innerHTML = ''; \/\/ Clear existing content\n\t\t\t\n\t\t\tlet videoSourceClass = 'fallback-error';\n\t\t\t\n\t\t\tif (isChineseLang) {\n\t\t\t\tif (bynderID) {\n\t\t\t\t\tvideoSourceClass = 'bynder';\n\t\t\t\t}\n\t\t\t} else {\n\t\t\t\tif (isValidYouTube) {\n\t\t\t\t\tvideoSourceClass = 'youtube';\n\t\t\t\t} else if (bynderID) {\n\t\t\t\t\tvideoSourceClass = 'bynder';\n\t\t\t\t}\n\t\t\t}\n\t\t\t\n\t\t\t\/\/ Apply layout class (used in SCSS)\n\t\t\tmediaVideoElement.className = 'video ' + videoSourceClass;\n\t\t\n\t\t\t\/\/ CASE: Chinese language\n\t\t\tif (isChineseLang) {\n\t\t\t\tif (bynderID) {\n\t\t\t\t\t\/\/ Load Bynder\n\t\t\t\t\tif (!document.getElementById('bynder-widgets-js')) {\n\t\t\t\t\t\tconst script = document.createElement('script');\n\t\t\t\t\t\tscript.src = 'https:\/\/d8ejoa1fys2rk.cloudfront.net\/bynder-embed\/latest\/bynder-embed.js';\n\t\t\t\t\t\tscript.id = 'bynder-widgets-js';\n\t\t\t\t\t\tscript.setAttribute('data-account-url', 'https:\/\/brandcenter.flex.com');\n\t\t\t\t\t\tscript.setAttribute('data-language', 'zh');\n\t\t\t\t\t\tdocument.body.appendChild(script);\n\t\t\t\t\t}\n\t\t\n\t\t\t\t\tconst bynderDiv = document.createElement('div');\n\t\t\t\t\tbynderDiv.id = 'bynder-id_69d909aa0ae19';\n\t\t\t\t\tbynderDiv.className = 'video-bynder';\n\t\t\t\t\tbynderDiv.setAttribute('data-bynder-widget', 'video-item');\n\t\t\t\t\tbynderDiv.setAttribute('data-media-id', bynderID);\n\t\t\t\t\tmediaVideoElement.appendChild(bynderDiv);\n\t\t\n\t\t\t\t\tsetTimeout(() => {\n\t\t\t\t\t\tif (typeof BynderEmbed !== 'undefined' && typeof BynderEmbed.load === 'function') {\n\t\t\t\t\t\t\tBynderEmbed.load();\n\t\t\t\t\t\t}\n\t\t\t\t\t}, 500);\n\t\t\t\t} else {\n\t\t\t\t\t\/\/ No Bynder = error (even if YouTube is valid)\n\t\t\t\t\tshowVideoError();\n\t\t\t\t}\n\t\t\n\t\t\t\/\/ CASE: Not Chinese\n\t\t\t} else {\n\t\t\t\tif (isValidYouTube) {\n\t\t\t\t\tconst iframe = document.createElement('iframe');\n\t\t\t\t\tiframe.id = 'youtube-id_69d909aa0ae19';\n\t\t\t\t\tiframe.className = 'video-youtube';\n\t\t\t\t\tiframe.src = 'https:\/\/www.youtube.com\/embed\/' + youtubeVideoId + '?rel=0';\n\t\t\t\t\tiframe.frameBorder = '0';\n\t\t\t\t\tiframe.playsInline = true;\n\t\t\t\t\tiframe.allow = 'encrypted-media';\n\t\t\t\t\tiframe.allowFullscreen = true;\n\t\t\t\t\tmediaVideoElement.appendChild(iframe);\n\t\t\t\t} else if (bynderID) {\n\t\t\t\t\t\/\/ Load Bynder (fallback if no YouTube)\n\t\t\t\t\tif (!document.getElementById('bynder-widgets-js')) {\n\t\t\t\t\t\tconst script = document.createElement('script');\n\t\t\t\t\t\tscript.src = 'https:\/\/d8ejoa1fys2rk.cloudfront.net\/bynder-embed\/latest\/bynder-embed.js';\n\t\t\t\t\t\tscript.id = 'bynder-widgets-js';\n\t\t\t\t\t\tscript.setAttribute('data-account-url', 'https:\/\/brandcenter.flex.com');\n\t\t\t\t\t\tscript.setAttribute('data-language', currentLanguage);\n\t\t\t\t\t\tdocument.body.appendChild(script);\n\t\t\t\t\t}\n\t\t\n\t\t\t\t\tconst bynderDiv = document.createElement('div');\n\t\t\t\t\tbynderDiv.id = 'bynder-id_69d909aa0ae19';\n\t\t\t\t\tbynderDiv.className = 'video-bynder';\n\t\t\t\t\tbynderDiv.setAttribute('data-bynder-widget', 'video-item');\n\t\t\t\t\tbynderDiv.setAttribute('data-media-id', bynderID);\n\t\t\t\t\tmediaVideoElement.appendChild(bynderDiv);\n\t\t\n\t\t\t\t\tsetTimeout(() => {\n\t\t\t\t\t\tif (typeof BynderEmbed !== 'undefined' && typeof BynderEmbed.load === 'function') {\n\t\t\t\t\t\t\tBynderEmbed.load();\n\t\t\t\t\t\t}\n\t\t\t\t\t}, 500);\n\t\t\t\t} else {\n\t\t\t\t\t\/\/ No valid YouTube or Bynder = error\n\t\t\t\t\tshowVideoError();\n\t\t\t\t}\n\t\t\t}\n\t\t\n\t\t\tfunction showVideoError() {\n\t\t\t\tconst errorDiv = document.createElement('div');\n\t\t\t\terrorDiv.id = 'video-error-id_69d909aa0ae19';\n\t\t\t\terrorDiv.className = 'video-error';\n\t\t\t\terrorDiv.innerHTML = `\n\t\t\t\t\t<div>\n\t\t\t\t\t\t<h3>Video Unavailable<\/h3>\n\t\t\t\t\t\t<p>The content you\u2019re seeking is momentarily unavailable.
