Description

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, I2C interface works ａｎｄ the consumption is less than 10μA.
The device requires only 2.4V~5.5V single power supply. An I2C compatible interface ｉｎ 400kHz fast mode is provided, the device address is 64h.
AW2026 is available ｉｎ a DFN 1.5mm×1.5mm× 0.45mm-8L package.
