Overview

NCP1219 は、成功した 7 ピン電流モードの NCP12XX 製品シリーズとピン互換の新世代です。調整可能なスキップ・モードを利用し、高電圧スタートアップ FET を内蔵することにより、スタンバイ電力消費に優れています。内部周波数ジッタリング、ランプ補償、タイマベースの障害検出、ラッチ入力により、頑丈さとコンポーネント・コストが主な制約であるコンバータの有力候補となります。ダイナミック自己給電 (DSS) によりトランスフォーマ設計が大幅にシンプル化するので、NCP1219 の電源供給では補助巻線を使用しなくてもよくなります。この特長は、動作中の出力電圧が変動するアプリケーション (バッテリ充電器など) で特に有用です。その高電圧テクノロジにより、IC は高電圧 DC レールへ直接接続されます。

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.)
