公司介绍
NCP1597B 为 1 MHz 固定频率、高输出电流、同步 PWM 转换器,集成了低电阻、高压侧 P 沟道 MOSFET 以及低压侧 N 沟道 MOSFET。 NCP1597B 利用电流模式控制提供了快速瞬变响应和卓越的环路稳定性。它将 4.0 V 至 5.5 V 的输入电压调节为低至 0.8 V 的输出电压,能够提供高达 2 A 的电流。 NCP1597B 具有固定内部开关频率 (FSW)、限制涌入电流的内部软启动等特性。 通过使用 EN 引脚,关断电源电流降至最大 3 µA。 其他特性包括按周期电流限制、短路保护、低漏模式、节电模式和高温关断。 对于 NCP1597A,该零件还采用 6 引脚 3x3mm DFN 封装。

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.)
