Overview

NCP1570 は、低電圧降圧コントローラです。DC-DC 電源ソリューションの制御を提供し、広い電流範囲で 0.985 V という低い出力電圧を生成します。NCP1570 ベースのソリューションは、12 V から給電され、出力は 5 V 電源から得られます。これには、V2™ 制御方式を使用する同期 NFET 降圧レギュレータに必要なすべての回路が含まれ、可能な限り最速の過渡応答と最高の総合レギュレーションを実現します。NCP1570 は、固定内部 200 kHz 周波数で動作し、SO-8 にパッケージされています。NCP1570 は、低電圧ロックアウト保護、ソフト・スタート、遅延付きパワー・グッド、および組み込み適応型非オーバーラップを提供します。
