方案
By Technology
NCP1252控制器提供了构建具性价比且可靠的AC-DC开关电源所需要的一切,专用于ATX电源或其他任何正向应用。由于使用内部固定的计时器,NCP1252能够在不依赖辅助Vcc的情况下检测出输出过载。欠压输入针对低输入电压提供保护,提高了转换器的安全性。最后,SOIC-8封装节省有助于节省PCB空间,是成本敏感项目的优选方案。

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.)
