12v to 7.5v Help

If you're making a portable you probably need something to watch it on. (Unless you want to guess what's happening in the game, but I wouldn't advise that) Anyway, this forum is your "Hacking a pocket TV/screen" one-stop solution. Share your experiences and knowledge here.

12v to 7.5v Help

Post by NateN34 »

Hi,

I am wondering if this would be able to take the power of a 12v, 6A DC adapter or would that be too many amps?

Thanks in advanced

It doesn't matter how many amps the power supply can put out. It matters how many amps the device you are hooking up at 7.5v will pull. That switching regulator handles 1.5A. If the screen or whatever you hook up to it does not require over around 1.4A it will be fine.

Oh, thanks. I'm in the beggining taking a Electronics Class right now in college, so I don't know too much yet.

think about it this way; Amps are drawn. The component only takes as much as is needed, when there's not enough, you get problems. It's basically just an "amount". Voltage is more like an attribute and if it's wrong, that can cause problems.
