To match the brightness and color of multiple LEDs in RGB applications you should drive all LEDs with a constant current. However, some of these driver ICs require the complication of microprocessor ...
Suited for large-form-factor color displays, the TLC5940 and TLC5923 16-channel, constant-current-sink LED drivers offer a 30-MHz data transfer rate, a 1% channel-to-channel accuracy, and a 2.7% ...
