概览

FL6961 是一款通用照明功率控制器，用于需要功率因数校正的大功率照明应用。它设计为在边界模式下运行的反激或升压转换器。FL6961 提供控制的导通时间，可调节输出直流电压，实现自然的功率因数校正。外部开关的最大导通时间可编程，确保交流欠电压期间的安全运行。内置了一个创新的多矢量误差放大器，可提供快速瞬变响应和精确的输出电压箝位。一个内置电路可在输出反馈回路开路时禁用控制器。启动电流低于 20µA，运行电流已降至 6mA 以下。供电电压最高可达 25V，最大程度提高了应用灵活性。

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.)
