Hi all,

I'm looking for an LED driver that can drive RGB LED's multiplexed. I'm=20
working on a project for a customer that needs to have approx 120 RGB=20
LED's (so 360 individual segments) in a thin strip of under 1 sq inch,=20
so space is *TIGHT*.  The elements need to be addressed individually.

So far the LEDs will fit, and I can make a bit more space available for=20
drive transistors and processor(s) to control the LEDs.  I've found that=20
it's far easier to route 8 groups of (up to) 16 LED's than multiplexing=20
everything into one big processor, and I can use some small 4x4 QFN=20
processors for each group.  But before I go out and re-engineer that=20
wheel, I'm wondering if there are existing drivers that will do this=20
easily, and hopefully have internal switches to save adding a ton of FET=20
switches.  I'd think groups of 8 to 24 LEDs (24 to 72 segments) should=20
be fine.  And I'm expecting the segments to be run at 5-10 mA, though=20
that will be determined once a test prototype is built.

Thanks,
-Neil.
