Overview

CAT3200HU2 はスイッチ・キャパシタ・ブースト・コンバータで、低ノイズ、安定化出力電圧を実現します。CAT3200HU2 は、FB ピンがグランドに接続されているときに、固定安定化 5 V 出力を提供します。それ以外の場合は、外部抵抗器を使用して、調整可能出力を提供します。一定周波数 2 MHz チャージ・ポンプにより、小型 1 µF セラミック・キャパシタが使用できます。広い範囲の入力電源電圧で最大 100 mA までの出力負荷をサポートでき、バッテリ駆動アプリケーションに最適です。シャットダウン制御入力によりデバイスをパワーダウン・モードにすることができ、電源電流を 1 µA 未満に低減します。短絡または過負荷状態の場合、デバイスはフォールドバック電流制限と熱的過負荷検出の両機能により完全保護されます。さらに、ソフト・スタート、スルーレート制御回路が電源起動中の高突入電流を制限します。

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.)
