1、概述：
深圳市振邦微科技现货推出一款输入2.5V~5V转输出3.3V电流1.5A手电筒专用IC，AH6700A是一颗五功能手电筒LED驱动芯片，采用了极小的SOT23无铅封装形式，2.5V~5V转3.3V，仅需一颗电容器件，既节省PCB空间，又节省系统的成本，三节干电池或一节锂电池可以驱动1-5W的LED。AH6700A 过开关断开再接通来变换输出模式，可以实现亮度调节和暴闪功能。AH6700A可工作于-40℃~+85℃
Shenzhen Zhenbang micro technology has launched a special IC for flashlight with input of 2.5V ~ 5V to output of 3.3V and current of 1.5A. Ah6700a is a five function led driver chip for flashlight, which adopts a very small SOT23 lead-free package. 2.5V ~ 5V to 3.3V requires only one capacitor device, which not only saves PCB space, but also saves system cost. Three dry batteries or one lithium battery can drive 1-5w led. Ah6700a switches off and then on to change the output mode, which can realize brightness adjustment and flash burst functions. Ah6700a can work at - 40 ℃ ~ + 85 ℃
