Re: Solytech with no 2 transistor 5vsb circuit?
>higher frequency = smaller transformer.
should be...but in the pics 370 posted +5vstby trafo actually looks a bit bigger than average....then again it's still rosewill..heh
>The ICE2A0565Z in my Antec Earthwatts also runs at 67 Khz. I wonder why Solytech wants to run at the higher frequency???
i would say trend (in the indistry) is probably to use higher and higher freq. as probably efficiency rises with the freq.(the stuff stj said about size).
as for does it REALLY gain anything, no, i wouldn't say so...i would say 67khz is perfectly fine....overall i would like to see this freq. go down, not up (that would mean less strain to components), but that would mean bigger trafos, yes...
i would actually go to the extreme(like i mentioned some time ago) and make +5vstby a linear supply. that would surely outlast any smps design. stress is practically non-existant with linear supplies. 1A design would probably suffice(as who actually utilises full 2A from +5vstby?).
