The TCA62724FM is an optimal constant-current LED driver for RGB pixel LEDs.
The TCA62724FM supports 16 dimming states for each color in the RGB pixel LED setup, resulting in 4096 colors for carrying out illumination by internal PWM.Moreover, it is not necessary to connect external resistance to an output in almost all cases.The forward current of the LED is set up using the external resistor.
