Overview

NCL30288 は AC-DC 力率改善フライバック・コントローラで、ターゲットは絶縁/非絶縁バックブースト/SEPIC 定電流 LED ドライバです。擬似共振モードで動作するため、効率が最適になります。新しい制御メソッドにより、プライマリ・サイドからの LED 定電流を厳密に調整できます。これにより、セカンダリ・サイドには、フィードバック回路、バイアシング、オプトカプラが必要なくなります。 高集積であるため、外付け部品の数が最小限になります。堅牢な安全保護スイートが組み込まれているので設計がシンプルになります。非常にコンパクトでスペース効率の高い設計を特に意図しています。

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.)
