FAN9673是一款交错式三通道连续导通模式(CCM)功率因数校正(PFC)控制器IC,用于 PFC 预稳压器。FAN9673结合了前沿、平均电流“升压”型功率因数校正电路,电源设计完全符合IEC1000-3-2规定。交错式运行大幅减少了输入和输出纹波电流,导通EMI 滤波变得更为简单和经济高效。
创新的沟道管理功能使次级沟道的功率电平能够根据CM引脚的设置电压进行平稳加载和卸载,提高了PFC转换器的负载瞬态响应。
FAN9673还结合了多种保护功能,包括峰值限流、输入电压掉电保护和TriFault Detect™功能。

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.)
