按技术分类
设计
FSQ500L专门设计用于替代低成本线性电源。该器件将电流模式脉宽调制器(PWM)与SenseFET整合在一起。集成的PWM控制器特性包括:固定振荡器、欠压闭锁(UVLO)保护、过载保护(OLP)、前沿消隐(LEB)、优化的栅极接通/关断驱动器、带滞后功能的热关断(TSD)保护和用于环路补偿的温度补偿精密电流源。与线性电源相比,FSQ500L器件的整体大小和重量都有所下降,同时其效率、生产力和系统可靠性得以增强。此器件提供了一个适合经济高效的反激式转换器的基础平台

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.)
