概览

NCP81141 是一款单相降压方案，适用于兼容 Intel VR12.6 的 CPU。该控制器组合了真正的差分电压感应、差分直感 DCR 电流感应、输入电压前馈和自适应电压定位，可为台式和笔记本应用提供准确调节的电源。该单相控制器使用 DCR 电流感应，针对动态负载事件提供最快的初始响应，且系统成本更低。NCP81141 结合了一个内部 MOSFET 驱动器，可提高系统能效。提供高性能运行误差放大器，简化了系统的补偿。专利动态参考注入避免了闭环瞬变响应和动态 VID 性能之间进行平衡的必要性，进一步简化了环路补偿。专利总电流合并提供了高准确度数字电流监控。

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.)
