A6280 3-Channel Constant-Current LED Driver

The A6280 is a 3-channel constant current LED driver that has a wide range of output currents. The A6280 controls LED brightness with a Pulse Width Modulation (PWM) scheme that gives the application the capability of displaying a billion colors in an RGB cluster. The maximum current is set by an ext.
