How to build-up a programmable current source

Dear all,

I would like to develop a programmable current source to feed less than 130 mW (for resistances of 4-10 Ohm). (Up to 150 mA)

Because I need so many, I would like to integrate them. I was wondering if with TI IC solutions there is a way to develop this circuit.

The resolution needed would be around 1 mA or 0.5 mA.

I have written in this forum since I believe that most of the drivers for LED require the same specifications.

Thanks in advance,

Daniel
