my led driver calls for 2 capacitors.
when running the 2 drivers from same power line in parallel, is it necessary to put 2 caps at each driver or can they share the caps?
or can i increase cap values and get by with 2 instead of 4?
thanks

I would place separate input decoupling capacitors near each IC even if they are physically close to each other. In that case the ESR of the capacitors are effectively in parallel.
