最大20Wまでの電力範囲では、1トランジスタ･フライバック、フォワード、または擬似共振トポロジを採用して、比較的高いスイッチング周波数で動作してトランスと出力コンデンサのサイズを最小化する高電力密度かつコスト効率に優れた絶縁型補助電源を設計できます。

STは、パワーMOSFET、PWMコントローラ、保護回路をワン･パッケージに集積し、超低スタンバイ電力、800V/900Vの高ブレークダウン電圧、各種の保護機能を備えた幅広い集積化高電圧コンバータの提供により、電源の効率最大化と信頼性向上をサポートしています。

さらに、製品開発期間の短縮を可能にする多種多様なハードウェアとソフトウェアの評価および開発ツールやリファレンス設計を提供しています。
