说明

The AW36404 is a low voltage-drop current sink LED driver, which supports both flash and torch modes. The current-regulation sink integrated in the chip makes the LED current be capable of keeping constant when input voltage, LED forward voltage or temperature are changing. The LED current can be adjusted among 64 steps by sending 1-wire pulses into the EN pin, and the maximum value is 400mA. For AW36404, only one multi-layer ceramic capacitor is needed for the peripheral of the solution. In shut down mode, the AW36404 turns off all internal circuit and the consumption is less than 1μA. The device requires 2.7V~5.5V input voltage range and an operating temperature range of -40℃~85℃.
