方案
By Technology
NCP81140 是一款多相降压方案,适用于可兼容 Intel VR12.5 的 CPU,带有 4/3/2/1 用户可配置相位。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。该控制系统基于组合了 DCR 电流感应的双缘脉宽调制 (PWM),提供了对于动态负载事件的最快速初始响应,降低了系统成本。它还可以在轻负载运行期间实现单相,并且可以在轻负载条件下自动进行频率缩放,同时保持优异的瞬变性能。

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.)
