Overview

NCP81255 は、パワー MOSFET を内蔵した高性能、低バイアス電流、単相レギュレータで、幅広いコンピューティング・アプリケーションのサポートを目的としています。このデバイスは、独自のインタフェースにより、調整可能な出力に最大 14 A TDC の出力電流を供給します。1.2 MHz までの高スイッチング周波数で動作するので、小型サイズのインダクタやキャパシタを採用できます。このコントローラは、オン・セミコンダクターの特許取得済み高性能 RPM 動作を利用します。RPM 制御は、過渡応答を最大にし、不連続周波数スケーリング動作と連続モード・フルパワー動作の遷移をスムーズにできます。NCP81255 は、高精度な電流モニタリング向けのプログラマブル・オフセット補償を備えた超低オフセット電流モニタ・アンプです。
