Description

AW3640 is a low voltage-drop current sink LED driver, which supports both Torch and Flash modes. The current-regulation sink integrated in the chip make the LED current capable of keeping constant when input voltage, LED forward voltage in temperature changing. The LED current can be adjusted among 16 steps by sending 1-wire pulse into the EN pin, and the maximum value is 200mA.
AW3640 is available in an ultra small 1.5mm× 1.0mm×0.55mm DFN-6L package. Ａｎｄ only one multi-layer ceramic capacitor is needed for the peripheral of the solution.
In shut down mode, AW3640 turns off all internal circuit and the consumption is less than 0.1μA.
The device requires 2.8V~5.5V input voltage range and an operating temperature range of -40~85℃.
