Overview

NCV891330 は、デュアル・モード・レギュレータで、最大 45V の入力電源で動作する必要がある車載用、バッテリ接続アプリケーションを意図しています。出力負荷に応じて、PWM 降圧コンバータまたは低ドロップアウト・リニア・レギュレータとして動作し、車載用ドライバ情報システムでよくある低ノイズと低静止電流の要件があるシステムに適しています。リセット・ピン (固定遅延あり) が、マイクロコントローラとのインタフェースを簡略化します。 NCV891330 には、電流制限、ショート保護、サーマル・シャットダウンなど、車載用電源システムを目的とした保護機能もあります。加えて、高周波のスイッチングにより、使用するインダクタ値が小さくても、全セラミック出力フィルタ・コンデンサ (スペース効率のよいスイッチング・レギュレータ・ソリューションを形成) であっても、低出力電圧リップルです。

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
