3-Channel Breathing LED Driver with IIC Interface

AW2026 is a three channels constant current LED driver. The max output current is 4-level selectable among 3mA, 6mA, 12mA and 25.5mA. Each LED is 256 current levels configurable so as to achieve 256*256*256 color mixing. The 256-level dimming and 12 bits PWM resolution create fine and smooth dimming effect even in low brightness. In shut down mode, AW2026 turns off all internal circuit and the consumption is less than 1μA. In standby mode, I 2 C interface works and the consumption is less than 10μA. The device requires only 2.4V~5.5V single power supply. An I 2 C compatible interface in 400kHz fast mode is provided, the device address is 64h. AW2026 is available in a DFN1.5mm×1.5mm×0.45mm -8L package.
