Overview

NCP1253 は高集積 PWM コントローラで、頑丈で高性能のオフライン電源が小型の TSOP-6 パッケージで実現できます。電源範囲は最大 28 V、ピーク電流モード制御で動作するジッタード 65 kHz/100 kHz のスイッチング回路をホストします。セカンダリ・サイドの電力が下がり始めると、スイッチング周波数を最低レベルの 26 kHz まで自動的にフォールドバックします。電力がさらに下がると、スキップ・サイクルへ移行してピーク電流を制限します。CCM 動作でのサブ・ハーモニック発振を回避するために、電流センス信号に単純な抵抗を直列に含めることにより、調整可能なスロープ補償を利用できます。自動回復タイマベースの短絡保護に加えて、Vcc ピンの過電圧保護は、フォトカプラの破壊や逆開ループ動作の場合に回路全体を保護します。

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.)
