If you’re modding and you want the most efficiency possible while also keeping a wide range of outputs available, look at Mike C’s driver(s) which use multiple channels to feed different banks of 7135s for different output levels. Only one 7135 ever gets PWM’d and the rest are grouped so that you get modes that use an exact number of 7135s for each level. It’s hard to describe in such general terms. You should just look at his thread and see for yourself how he did it.
