Hi there e2e,

I am looking for an RGB LED driver and found some but not to my specific requirements.

Looking for a design guide to create RGB waves.

Thanks

Hi Monet,

The final solution will be used in an Autonomous Mobile Robot. The solution is intended to show the mode of the device using different colors and create an RGB wave for cosmetic purposes.

Have found many automotive & industrial-grade RGB drivers but unable to find a device or design guide that can suggest a way forward for RGB waves.

Hi Akash,

Several devices can achieve your request which depend on your spec. How much RGB LED do you want to drive? How much current are you targeting? which controller are you using to control the LED Driver?

Hi Monet,

RGB per board would be 24 to 48max, current about 45mA per LED (current may change based on LED).
