概览

NCP1616 是一款高电压 PFC 控制器，可基于创新的电流控制频率折回 (CCFF) 模式驱动 PFC 升压级。在此模式下，当电感器电流超过编程值时，该电路以临界导通模式 (CrM) 运行。当电流低于此预设水平时，NCP1616 会将频率线性下降，在正弦零交叉处降至最小 26kHz。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。创新电路即使在开关频率降低时也能实现接近一致的功率因数。 集成的高电压启动电路无需外部启动组件，在正常运行期间的功耗非常少。NCP1616 采用 SOIC-9 封装，具有坚固紧凑的 PFC 级所需的功能，且外部组件很少。

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.)
