Hi, Sivasuryan,

We have several such kind of RGB LED drivers.

How many channels do you need?

And you can take a look at LP5562 and LP5569.

We need three channels - 1 led for red, 1 led for Green and 1 led for blue. We need to make true white light with these three LEDs (RGB LEDs).

Thanks and regards,

R.Sivasuryan
