データ･センターの電源要件は絶えず拡大しており、従来の電源システムは、利用拡大によるこの負荷の増大に対応するには、もはや十分ではありません。

パワー･ディストリビューション･チェーン（フロントエンドAC-DC段から、バックエンドDC-DCパワー･ディストリビューションまで）は、効率、電力密度、デジタル機器とのインタフェース機能の面で、最大限の性能を発揮する必要があります。負荷再分配、動的資源配分、仮想化など、さまざまな戦略により、エネルギーの最適な利用を実現する必要があります。

STは、ディストリビューション･チェーン全体にわたり最適化された電源設計を実現するための多種多様な製品やソリューションを提供しています。STのデジタル/アナログ･コントローラとMOSFETやドライバは、極めて効率的かつ高密度のAC-DC電源供給を実装するための重要な構成要素です。バックエンドDC-DCパワー･ディストリビューションにおいて、STは、ポイント･オブ･ロード変換や最近開発された革新的な48V DC電源からのDC-DC変換向けに先進的なソリューションを提供しています。
