概览

FAN5331 是一款通用型、固定频率升压转换器，适合在高开关频率下运行，可最大程度降低手持通信设备电池端子处测量的开关噪声。正常和关断模式下的静止电流非常小，可延长电池寿命。通过逻辑电平关断电路可以选择正常运行或关断模式。内部 N 沟道的低导通电阻可确保高能效和低功耗。按周期电流限制电路会将开关的峰值电流保持在 1A 典型值以下。FAN5331 采用 5 引线 SOT-23 封装。

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.)
