By Technology
FAN5640 适用于通过恒定高压侧电流源驱动一个或两个串联的键盘 LED 串。该器件最多可以每沟道 25 mA 的电流驱动四个串联的白色 LED。如果不需要第二沟道,这些沟道则联接在一起将输出电流升压至最高 50 mA。外部电阻可编程最大输出电流。调光可通过启用引脚或输入电源轨的脉冲调制实现。

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.)
