フライバック、フォワード、絶縁コントローラ
アナログ・デバイセズのフライバックおよびフォワード・コントローラのポートフォリオは、絶縁型および非絶縁型アプリケーションで使用されるDC/DCコンバータ・ブリックのシンプルで費用対効果の高い代替品を提供します。フライバック・コントローラを使うと最大100W、フォワード・コントローラでは最大数キロワットの電力を得ることができます。アナログ・デバイセズが独自に開発したiCoupler®技術がいくつかのフォワード・コントローラに集積されているため、アイソレーションの境界を越えて信号を伝送する大きな信号トランスおよびフォトカプラが不要です。多くのフライバック・コントローラにはフォトカプラが不要なため、設計の複雑さやコストが削減され、同時にシステム全体の信頼性が向上します。どちらのトポロジについても既製のトランスがいくつか製品データシートに記載されています。これらのトランスでは設計が更にシンプルになっており、市場投入までの時間を最大限に短縮できます。
