Overview

NCP81234 は DrMOS パワー・ステージで動作するようにシングルまたはデュアル出力レギュレータとして構成できます。このデバイスは 4.5V ～ 24V の範囲で動作し、プロセッサ、DDR メモリ、および FPGA への給電に最適です。デュアル制御ループを提供し、高度な 2 相ソリューションの出力を並列する機能で各ループの動作を独立させることができますこのコントローラにより差動電流センスと電圧センスの精度が高くなります。DCR 電流センスをサポートし、または DrMOS からの IMON 信号にも対応できます。このパーツには過電流、過/低電圧からの保護に加え、過熱保護もあります。
