color: #37a6d9;font-size: 1.1rem;"> RT7084 </a> 採用「先煞車再驅動」策略,確保風扇能快速恢復正轉,顯著提升啟動穩定性。 </li> <li><b>如何突破風扇模組空間限制?</b><br> 伺服器風扇模組僅有 4×4 公分的緊湊尺寸,對電源與控制晶片的整合度要求極高。RT7084 採用 4mm×4mm QFN 封裝,將 MCU、Gate Driver 與 Buck 轉換器整合於單一晶片,大幅簡化 PCB 佈局並有效降低 BOM 成本。 </li> <li><b>如何縮短產品開發週期?</b><br> AI 系統開發時程緊湊,軟體開發往往成為導入瓶頸之一。<a href="https://www.richtek.com/RedirectToProduct?specid=RT7084C2M&utm_source=Newsletter&utm_medium=RTWWW&utm_campaign=Issue54TW&sc_lang=zh-TW" target="_blank" style="text-decoration: none;
