六通道、一线脉冲计数调光、1 倍和1.5 倍自适应切换 共阳并联 LED 驱动器

CP2166是一款共阳极1倍/1.5倍自适应电荷泵型LED驱动器。它允许较宽的电源电压范围，特别适合于锂电池供电设备。CP2166通过内部电阻设置LED电流，每通道的电流可高达27mA。CP2166可根据电源电压和负载的情况，在两种工作模式间自适应切换，提高了工作效率。同时采用了独有的电流自动镜像技术，使LED的电流匹配度不随LED的导通压降差而变化。CP2166采用一线脉冲计数调光方式，LED亮度分32步对数可调。CP2166只需两个1μF的输入输出电容和两个1μF的电荷泵电容。优越的电路控制特性保证了低的电源冲击电流和EMI。CP2166 关机电流小于0.1μA。\n产品详情 - 驱动多达6个LED，每个LED最大电流：27mA\n- 电流匹配精度：3% （典型值）\n- Auto-Mirror技术确保在各并联白光LED导通压差较大的情况下较好的电流匹配度\n- 工作模式可根据输入电压和负载情况，自适应切换，使效率高达90％以上\n- 采用一线脉冲计数调光方式，LED亮度分32 步对数可调\n- 支持主副屏应用（EN2内置下拉电阻，当EN2为低时D1～D6工作；当EN2为高时，D1～D4关闭，D5、D6工作）\n- 低输入电流波动和低EMI\n- 无需外围电感\n- 开关频率：1MHz\n- 过流保护、过热保护和过压保护\n- 工作电压范围：2.7V~5.5;
