dc42, I'm really looking for discrete control over the lights and would prefer to sacrifice number rather than discrete control
Mike, I've never used that driver before, though it looks solid for the purpose. My only concern is, without sample code out there, I worry I'll waste time when coding. The TLC5940 gives me the same inputs and also comes in HTSSOP28, but has the advantage of being the devil I know, if you get my meaning. If I'm not going to get additional outputs, I figure it might be best to chain up four 5940's. Heck, if I went QFN, the supporting components would take up more space than the devices themselves. (I can hear you shouting DECOUPLING!) in my ear.
