48 Vからの直接デジタル電力変換

STは、3つの新しい高性能電力変換ICを導入することで48 Vからの直接デジタル電力変換の実装を可能にし、データセンター・アプリケーションの全範囲をサポートします。 この3つの新しいICは、12 V/500 Wで97%を超えるクラス最高の電力効率により、36~72 Vの入力電圧、0.5~12 Vの出力電圧で堅牢かつ高い効率で動作します。 さらに、インテルのVR12.5(HaswellおよびBroadwell)、VR13(Skylake)、DDR3/4電圧制御規格、ならびにデータセンター・アプリケーション向けFPGAおよびASICのすべてに完全に準拠しています。
48 Vからの直接デジタル電力変換では中間の変換ステージが不要なため、データセンターでの電力損失が大幅に低減され、設置面積、冷却要件、および費用が削減されます。

3つの新しいICとは、

STRG02(予測型ZVSおよびZCS制御機能を備えた2次側コントローラ)、
STRG04(高性能60 Vフルブリッジ・ドライバ)、および
STRG06(50 W~300 W超の出力電力に対応するスケーラブルなデジタル・パワー・コントローラ(最大6つのコンバータを並列制御可能))です。 エネルギー比例制御、適応型インタリーブ、電流共用機能、および広範なPMBus™コマンド一式を実装しています。
