How to get Constant Current output using Constant Voltage Driver?

Hello Guys,

I am using a constant voltage driver (MAX: 45W) to drive RGB Leds (low power) .

Now i need to drive High Power Leds and for which i have to use Constant current driver.

I thought to use LT3956 which could convert constant voltage to constant current output , but the problem is that it has only one channel.

Where as i need RGB, three channels in the Output.

Any help shall be appreciated

Thank you very much.

Sounds to me like you are going to have to use 3 of the LT3956 constant current devices if you want to control each LED seperately.
