General Description

The A6281 is a 3-channel constant current LED driver that has a wide range of output currents.

The A6281 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 external resistor.
