I'm trying to find a viable IC for a project, but all my searches are being bogged down in clutter.
I want to drive a couple of RGB LEDs via a serial type link. The annoyance is I need PWM on them and quite a few.
Effectively I need a shift register type IC with about 6 outputs with PWM. I'm not worried current wise, since I am driving it through a darlington array IC.
The best I have found so far is the TLC5940 (http://www.mouser.com/ds/2/405/slvs515c-197949.pdf) at £2.29 ea this is massively overkill output wise though at 16.
Does anyone know anything more cost effective?
