Overview

NCP1395A/B には、信頼性が高く頑丈な共振モード電源を構築するのに必要なものすべてがあります。OR 機能を要する場合 (複数のフィードバック・パス実装など) に 1 kHz 電圧コントローラ発振器の制御モードによって柔軟性を持たせるなど独自のアーキテクチャになっています。保護機能 (即時シャットダウンまたはタイマベースのイベント、電圧低下、オプトカプラ故障検知など) はリアクション時間がそれぞれ異なりますが、さらに安全なコンバータ設計ができるようになり、回路がさらに複雑になることがありません。デッドタイムが調整可能なので、スイッチング周波数が上昇するにつれて高くなるシュートスルー電流も低く抑えます。最後に、オンボード相互コンダクタンス・オペアンプにより、定出力電流調整動作モードや従来型の電圧調整など、さまざまな構成が可能になります。

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.)
