公司介绍
FL7733A 是一款带有先进的初级侧调节 (PSR) 技术的高度集成 PWM 控制器,可最大程度减少中小功率 LED 照明转换器中的部件数量。此 LED 驱动器使用创新的 TRUECURRENT® 技术提供允差范围较小的恒定电流输出,可在通用线路电压范围内实现恒定电流 (CC) 允差小于 ±1% 的设计,满足严格的 LED 亮度要求。由于最大程度降低了打开时间波动,在 FL7733A 中实现了基于通用线路范围的高功率因数和低 THD。集成式高电压启动电路实施了快速启动和高系统能效。在启动过程中,自适应反馈回路控制会预计稳态条件,并将初始反馈条件设置在稳态附近,以确保不会发生 LED 电流超射或下冲。FL7733A 还提供强大的保护,如 LED 短路/开路、输出二极管短路、传感电阻短路/开路以及温度过高,实现高系统可用性。FL7733A 控制器采用 8 引脚小型封装 (SOP)。

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.)
