FAN5341 是一款异步恒定电流 LED 驱动器,能够有效为最多五个串联的 LED 串提供最多 500mW。1.2MHz 的固定开关频率针对小尺寸应用进行过优化,允许使用小芯片电感器和电容器。FAN5341 采用简单的单线数字控制接口,通过应用数字脉冲,以 32 线性步进对 LED 的亮度进行编程。安全起见,该器件具有集成过电压、过电流、短路检测和高温关断保护。另外,如果电池电压过低,则会触发输入欠压锁定保护。FAN5341 采用极薄款 2mm x 2mm x 0.55mm 6 引线 UMLP 封装,符合绿色和 RoHS 标准。

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.)
