NCP4353 和 NCP4354 是辅助侧 SMPS 控制器,用于需要极低无负载功耗的应用。此器件能够检测无负载条件,并让电源进入低功耗关闭模式。在关闭模式下,关闭初级侧控制器,能量由输出电容提供,因此消除了保持调节所需的功耗。在关闭模式下,输出电压松弛,可降至可调电平。需要更多能量时,NCP4353 或 NCP4354 会自动重新启动初级侧控制器。在正常供电中,这些器件提供集成式电压反馈调节,无需分路稳压器。除电压调节外,A 版本还包含一个电流调节回路。一个光耦合器即可提供反馈控制和 ONOFF 信号。NCP4354 包括一个使用 1 kHz 方形波驱动的开路 MOSFET 实施的 LED 驱动器引脚,以 12.5% 占空比运行,以用于指示。NCP4354 采用 SOIC-8 封装,NCP4353 采用 TSOP-6 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.)
