RGB LED driver controller

I have a 10w RGB LED package (3w per colour) and need to drive it so we can select:

Just red

Just green

Just blue

White (all three together)

Yellow (red & green together)

Each of the LED's requires different voltages, and current limited to 350mA per channel.

I tried previously to do this, but with little success and just destroyed the LED's.

To limit the current I tried adding NSI50350ADT4G's, but they get VERY hot so dont think this is a usable solution. Also, as they get hot, the current goes down so not a great idea.

The LED's are common anode

Here's a link for the LED


I've uploaded an image of the original Chinese flood light controller, but dont want to use the IR remote. Must be via a single N/O switch.

I want to control the colour by pressing a N/O switch. Each time it's pressed, it changes to the next colour.

Once tested on an arduino, I plan to build it on a ATMEGA328-AU chip.

There are lots of circuit ideas out there about how to manage voltage and current for these LED's, but no guess work please. If you dont have the skill and knowledge, dont bid.

This is a re-posted project as it was given to a freelancer without the appropriate electronics knowledge to complete it properly.

Hello, First of all, selecting NSI50350ADT4G is a wrong decision as it is a linear converter. That means any unused energy is consumed on this IC and produces a lot of heat. When the temperature reach the thermal sh Lisää
