Has Anybody Tried 12v in the PSone Screen?

The reason being I want to use the voltage from my N64 battery to power the screen without frying it. I would rather not have to use a dc-dc converter if possible, because converting from 12 to 7 to 5 just seems dumb. Sorry if this has been asked before, I couldn't find anything in the search.

well...it shouldn't damage anything...

The N64 can take 7v to the 12v input, its just going to a 7805 regulator so its going down to 5v anyway. Just use batteries that output 7.2 volts. Then the only dc-dc converter you'll need it to knock the power down to 3.3v for the N64.

I dunno, I tried 9.6v on it once and the picture was distorted a lot.....Ben used a 9v battery on his psone screen for the PS2p, though......

what can a 7805 take? 14V max? its something like that....

I tried 12v before....it won't fry the screen but you certainly can't play anything on it.

the minimum voltage for a 7805 is 7.2v, the maximum is 36v......that makes me think that the psone screen doesn't just run off one or two 7805s if when you start putting in higer voltages in gets screwed up.......

put a regulator infront of the line?

better, a dc-dc converter so that you dont waste the power as heat!

ouch. after i said the maximum was 14V, i just got told by gameleveler!

Could you use a 5v switching regulator and bypass them?

I don't know, but you can always use an adjustable regulator if you have enough power going in. Then just adjust it to, say, 7.5 volts. Perfect for the lcd, but it's still a regulator, so heat's still a small issue.

you dont need adjustable they make 780X regulators in 7, 8 and many other voltages!

Okay heres what I got, I tried 12v in the screen and it turned on but was COMPLETELY distorted with lines all over the screen and stuff, a million miles from playable.
The 12v did not damage it luckily

So I guess it does need a DC-DC converter or a regulator.

So I was thinking that maybe I could run the screen AND the N64 board off a 7.5v DC-DC converter?

why not just use 7.2V for the n64 too? unless you only have a 12V battery.

12v at an amperage equal or lower than the PSOne screen can take is fine. Even a little higher. But too much amperage, and the screen wil blow. Even at 5v the screen can blow. I blew my first LCD at 5v becuase the amperage was probably twice the rated amps.
