Overview

NCP5331 は、64 ビット AMD Athlon プロセッサと低電圧、高電流電源に電力を供給する高度な制御機能を組み込んだ、第 2 世代の 2 相降圧コントローラです。 独自のマルチフェーズ・アーキテクチャにより、バランスの取れた負荷電流共有が保証され、出力電圧と入力電流リップルが減少し、フィルタ要件とインダクタ値が減少し、出力電流スルー・レートが増加します。 従来の拡張 V2 は、Vcore から内部 PWM コンパレータへの内部 PWM ランプおよび電圧フィードバックと直接組み合わされています。 これらの機能と拡張機能は、最速の過渡応答を提供し、出力電圧ジッタを低減し、設計の柔軟性と可搬性を高め、ソリューション全体のコストを最小限に抑えます。
