NCP12700 是一款固定频率、峰值电流模式PWM控制器,具有实施单端功率转换器拓扑结构所需的必要性能。这款器件支持高压启动,能够在宽输入范围内运行(9 – 120/200V MSOP10/WQFN10)并提供至少20mA电源,在系统启动期间为VCC提供临时偏置。这款控制器提供可调节软启动、输入电压支持欠压锁定(UVLO)保护以及可调节的过功率保护电路,会在输入电压提高时限制电路的总功率,简化系统散热设计。UVLO引脚还被配有一个关断比较器,允许通过外部信号禁用开关,将控制器切换至低静态电流模式。

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.)
