LED背光驱动-小家电控制器

BCT3222是一款高性能白色LED驱动芯片。BCT3222使用一个内部电阻来为6路LED灯的通道设置偏置电流，通道的电流匹配度在+/-1.5%。偏置电流随着电压波动变化很小，Dropout电压很低。BCT3222需要仅仅50mV的dropout 电压就能使通道输出20MA的电流并满足LED灯亮度要求。\n通过使用一个SEL引脚，BCT3222可以驱动六路并行的共阳或共阴白色LED, 可以调节电流值, 并能保持亮度一致。\nLED灯的亮度调节通过脉冲信号驱动EN引脚来实现. 电流可值从2.5mA到20mA, 共有8个亮度等级可供用户设置。内部的软启动电路可有效的减少开启和模式转换时的浪 ·驱动共阳或共阴LED\n·在通道电流20MA的情况下低至50mV的dropout 电压\n·饱和电流20MA\n·小于2%的LED电流匹配度\n·一线调节8个亮度等级控制\n·工作电压范围2.7V到5.5V\n·热关断保护\n·低输入噪声和电磁干扰\n·封装DFN-10L;
