Title: where's that 5v from?
Post by: dxecuter on April 24, 2008, 06:54:46 PM
hi! i was just wondering how is it possible to have a 5v point on the psp when the battery only gives 3.2V??? :confused:

Off the top of my head a charge pump, or up-converter, haven't really looked into it much though, so I could be wrong...

With a transformer, they work thanks to two inductances, i have studied them though i don't remembre very well. So you are getting more volts in the output than you have in the input but with a current limitation. For example if you have 3 volts and you want 6 volt you can get them but as far as the wattage has to be the same (in real life you would get less wattage in the output) you will have half the current in the output than you had in the input. Also these transformers works with AC so you need to transform your DC in AC using a MAX253 and an oscilator. So you need an oscilator, a max253 and a transformer. That's it.

yes he is right if u can decypher his technical lingo :tup:

simply DC/DC converter http://en.wikipedia.org/wiki/DC_to_DC_converter (http://en.wikipedia.org/wiki/DC_to_DC_converter)

oh! thanx alot...that was the type of response i waited, how to do and how it works...but still dont get the physics part of it...i would search about this, you gave me a good start thx :#1:
