QX5243 是一款、恒流、高效率的高亮度LED驱动器。通过外接一个电阻设定输出电流,通过DIM引脚实现辉度控制功能,输出驱动电流最大可达800mA。QX5243特别适合宽输入电压范围的应用。高端电流检测达到±5%的电流精度,同时只需很少的外接元件。由于采用滞环控制方式,QX5243对负载瞬变具有非常快的响应速度,对输入电压具有高的抑制比。电感电流纹波为20%。最高工作频率可到2MHz。工作温度范围从-40℃到125℃。采用SOP-8封装。 特 性
最大输出驱动电流可达800mA 高端电流检测 辉度控制 最大20KHz辉度控制频率 滞环控制:无需补偿 高达2MHz工作频率 ±5%电流精度 恒流输出 5.5V到36V输入电压 5V,2mA片上稳压器 -40℃到125℃工作温度范围 应用
建筑、工业、环境照明 汽车尾灯、雾灯、RCL、DRL 指示灯、应急灯 MR16 及其它LED 灯
