1次側および2次側レギュレーション、固定スイッチング周波数、擬似共振動作などのさまざまな実装では、一般にオフライン·コンバータで絶縁型/非絶縁型フライバック·トポロジが採用され、数Wから100Wの出力電力に対応します。回路の動作は単一スイッチ·トポロジに基づき、入力から得られた電力はパワー·スイッチがオンの間にトランスの1次インダクタンスに蓄えられ、パワー·スイッチがオフの間に2次側出力に送られます。

フライバック·トポロジでは、効率、電力密度、低スタンバイ電力、および信頼性を兼ね備えることが重要な要件です。

STは、幅広いコントローラ、パワーMOSFET、集積化高電圧コンバータ、ダイオード、プロテクション·デバイスに加え、さまざまなハードウェアとソフトウェアの開発および評価ツールの提供により、高効率のフライバックAC-DCコンバータの設計をサポートしています。
