概览

这PWM控制器集成功率因数校正和必要的准谐振反激控制器，成就紧凑和极高能效的AC-DC LED驱动器，用于高性能、低纹波的LED照明应用。PFC段利用专有乘法器架构，在采用临界导电模式工作时提供低谐波失真和接近1的功率因数。准谐振电流模式反激段包含专有谷底锁定电路，确保稳定的谷底开关工作，及在切换至频率反走模式之前在低至第4谷底工作，在超过第4谷底时采用最小频率钳位以消除噪声。跳周期模式提供极佳轻载能效，待机能耗极低，非常适合智能照明应用。

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.)
