Overview

NCP1575 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 0.980V という低い出力電圧を生成します。 これには、V2TM 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。 NCP1575 はデフォルトのスイッチング周波数 200kHz で動作しますが、スイッチング周波数は Rosc とグランドの間の追加の抵抗によりユーザがプログラム可能です。 このデバイスは、低電圧ロックアウト保護、ソフト・スタート、および組み込みの適応ノンオーバーラップを提供し、SO-8 パッケージで組み立てられます。
