パワー・スイッチ内蔵型昇降圧レギュレータ
アナログ・デバイセズのモノリシック昇降圧同期DC/DCコンバータは、大電流供給、およびシングルセル、マルチセルのバッテリ、スーパーキャパシタ・スタック、ACアダプタ電源などの広範囲の電源を使った動作に対応しています。独自の4スイッチPWM昇降圧トポロジにより、低ノイズでジッタのないスイッチングを全動作モードで提供し、電源ノイズに敏感なRFおよび高精度アナログ・アプリケーションに理想的です。独自の4個の内蔵MOSFETスイッチの組み合わせにより、降圧モードから100%ドロップアウト動作を経て昇圧モードへとシームレスに遷移し、入力電圧が出力の上下に変動しても固定の出力電圧になります。デバイスによっては、大電力供給のために並列に接続したり、太陽電池の充電やMPPT制御機能のために自動最大電力点追従（MPPT）を利用したりできます。
