I'm just saying that you should allow the highest voltage possible to the audio amp (like for the GC).ToastBucket said:But I'm stepping down for the higher current draw stuff and up for the lower current draw stuff. The buckboost has 96% efficiency and the step up has 90% (it's a PTN04050CAZ)
Also, the PTN04050CAZ has a minimum voltage of 2.95V, just so you know.
