描述 Description

AW2028H is three channels constant current LED driver with audio synchronization. The max output current is 4-level selectable among 9mA, 18mA, 37mA and 75mA. 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.
AW2028H integrates AGC preamplifier, ADC and digital filter to implement the audio synchronization, which allow user to synchronize the color LED with the audio input. The LED color can be programmed to switch periodically or vary directly with audio input signal. Multiple audio synchronization effects are configurable.
In shut down mode, AW2028H turn 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 65H.
AW2028H is available in a ultra-thin 8 pin FCQFN 1.2mmx1.2mmx0.37mm package.
