Overview

NCP3066 はモノリシック降圧/ブースト/反転スイッチング・レギュレータで、高輝度 LED を駆動するための定電流を供給するよう設計されています。超低フィードバック電圧 235 mV (標準) は、LED ストリングの平均電流を調整するのに使用されます。加えて、NCP3066 の入力電圧は最大 40 V と広く、照明アプリケーションでよく使用される 12 Vac / 12 Vdc 電源や、充電式電池のように調整されていない電源で動作できます。スイッチング・レギュレータ NCP3066 はステップ・ダウン (降圧)/ステップ・アップ (ブースト)/電圧反転トポロジで構成されており、外付け部品の数を最小限にします。NCV3066 の車載バージョン NCP3065 には ON/OFF 機能が付いていません。

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.)
