概览

NCP1612 是一款有源功率因数校正 (PFC) 控制器，专门用作 AC-DC 适配器、平板电视、照明镇流器和其他中等功率离线转换器中的升压预转换器。该控制器基于创新的电流控制频率折回 (CCFF) 方法。在此模式下，当电感器电流超过编程值时，该电路通常以临界导通模式 (CrM) 运行。当电流低于此预设水平时，NCP1612 会将频率线性下降，当电流为空值时大约降至 20 kHz。CCFF 可在标称负载和轻型负载下最大程度提高能效。尤其待机损耗降至最低。该控制器具有丰富的保护功能组合，可正确处理运行和故障情况下的电源阵列。 此器件具有专门的 PFC_Okay 输出，尤其适用于 LLC 控制器的 PFC 级。

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.)
