By Technology
NCP1379 是高性能器件,旨在为准谐振转换器供电。该控制器利用专有的谷锁闭系统,可以在功率负载变轻时进行切换并降低开关频率。这样将产生稳定的运行,即使在漏极-源极谷中总是触发的开关事件下也是如此。此系统可在低至第 4 个谷的条件下运行,并在之后切换到变频模式,确保出色的待机功率性能。为了提高过载条件下的安全性,该控制器包括了过功率保护 (OPP) 电路,可对高电平线路处提供的电源进行箝制。具有安全功能的固定内部计时器依赖反馈电压来检测故障。一旦计时器过期,控制器将停止并进入自动恢复模式,以确保低占空比突发操作。该控制器特别适合电视电源应用,具有低启动电压,允许使用辅助电源为设备供电。

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.)
