A6269 Description
TheA6269 is a linear, programmable current regulator providing up to 200 mA from each of two outputs to drive arrays of high brightness LEDs. The regulated LED current from each output, accurate to 5%, is set by a single reference resistor. Current matching in each string is better than 10% without the use of ballast resistors.
