マルチトポロジー DC/DC

アナログ・デバイセズのパワー・マネージメント製品の多くには、1 台または複数台のスイッチ・モード DC/DC レギュレータがさまざまな種類とトポロジーで組み込まれています。
このカテゴリの製品には 2 台以上のレギュレータがあり、1 つの小型パッケージに、降圧、昇圧、降圧/昇圧、SEPIC、反転スイッチング・レギュレータのいずれかまたは複数が組み合わせられています。また、製品によっては 1 台または複数台のリニア電圧レギュレータが組み込まれています。
これらのマルチトポロジー製品のアプリケーションには、高性能オペアンプおよびシグナル・コンディショニング回路用のスプリット正電源および負電源があります。または、単一のコンパクトな IC 内で複数の電源が組み合わせられています。
