外置MOS平均电流型LED降压恒流驱动器

TP8756是一款工作在固定关断时间控制模式的降压型LED恒流驱动器，用于高效地驱动多颗LED。TP8756采用平均电流型的闭环恒流方式，系统应用时输出电流对电感变化不敏感。这极大的提高了输出电流的恒流精度，特别适用于5~100V输入电压范围的非隔离降压LED恒流驱动电路。\n\nTP8756外置功率管，通过外部电阻可以设定LED输出的平均电流，并且通过MODE脚外接高低电平可以实现LED输出的高低亮模式切换。当MODE脚接高电平时，LED输出100%高亮模式，当MODE脚接低电平时，LED输出75%低亮模式。这只需要很少的外围元件即可以实现LED输出的高低亮模式切换，节约了系
