Something like the LM27951, I guess.

What are the exact voltages and currents you need?

I think this is the part I need.
I am using a TM4C129 hence 3.3V from a TPS73701 regulator.
The LEDs will be panel mounted indicators.
It will be an office environment so the LEDs would have to somewhat wide angle visible within that.
Two green and a red/green.
Those are the design parameters that govern my LED selection plus they would fall within the capabilities of the LM27951.
If you have had success with similar LED requirements I would appreciate your feedback.

I have noticed that the LM27951 does not seem to be a heavily stocked item.

Thank you for your assistance,
Victor

Similar devices would be LM2794 and LM27952.

I went with a TLC5916 with good results.

Thank you.
