Overview

NCP81239 USB Power Delivery（PD）コントローラは同期降圧ブーストで、ノートパソコン/タブレット/デスクトップ・システムその他USB PD標準C−Typeケーブルを使用する消費者向けデバイスの多くで要求される、バッテリ電圧/アダプタ電圧の電源レールへの変換に向けて最適化されています。NCP81239は、USB PD/C−Typeインターフェース・コントローラと併用する場合、USB Power Delivery仕様への完全準拠となります。 NCP81239は、電圧が入力電圧より高いか低いことを必要とするスルー・レート限定出力電圧を動的に制御することを要するアプリケーション向けに設計されています。NCP81239は、4つのNMOSFETスイッチを駆動することにより、降圧/ブーストや、USB Power Delivery仕様で規定されているコンシューマ/プロバイダ・ロール・スワップ機能のサポートができるため、すべてのUSB PDアプリケーションに適しています。USB PD降圧ブースト・コントローラは、電源/負荷範囲4.5 V～28 Vで動作します。

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.)
