概览

FAN9672是一款交错式双通道连续导通模式（CCM）功率因数校正（PFC）控制器IC，用于 PFC 预稳压器。FAN9672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。
FAN9672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.)
