TOSHIBA CMOS Integrated Circuits Silicon Monolithic
TCA62723FMG
Three-Channel Constant-Current LED Driver
The TCA62723FMG is an optimal constant-current LED driver for RGB pixel
LEDs.
This IC does not have to connect external resistance to each output in the
case of most. The output current of 3ch is set up by one external resistance.

1) Method of inputting analog voltage to terminal REXT
1. Precondition
Please set the range of the analog voltage input by 0 to 1.17V.
2. The maximum current is defined as αmA. (VADJ=0V)
α = 1.17×
