Overview

CS5141X 製品は 1.5A 降圧レギュレータ IC です。これらのデバイスは、260kHz と 520kHz で動作する固定周波数です。レギュレータは V2 制御アーキテクチャを使用して、優れた過渡応答、最適な全体のレギュレーション、および今日の高速ロジックに対する最も単純なループ補償を提供します。これらの製品は、4.5V ～ 40V の入力電圧に対応します。CS51411 および CS51413 には同期回路があります。CS51412 および CS51414 には、特に高入力電圧、軽負荷状態で効率を改善するために、外部 3.3V ～ 6V 電源からコントローラに電力を供給するオプションがあります。オンチップ NPN トランジスタは、最小 1.5A の出力電流を供給でき、飽和を保証するために外部「ブースト」コンデンサによってバイアスされるため、オンチップ電力損失を最小限に抑えることができます。保護回路には、サーマル・シャットダウン、サイクルごとの電流制限、周波数フォールドバックが含まれます。CS51411 および CS51413 は、LT1375 と機能的にピン互換です。CS51412 および CS51414 は、LT1376 と機能的にピン互換です。
