5 volt to 12 volt

butters · May 25, 2009

is it possible to convert a 5 volt power source to a 12 volt?
thanks.

Give more details.

Such as:
5v AC or DC?
Current available at 5v
Current required at 12v
How much do you want to spend?

hi,
Yes its possible to convert the voltage, look at switched mode power supplies, SMPS. Pick a type that gives the current output you require,

its 5V DC.. im not sure about the current..
i just need to know what is need to convert them..
current will check it out soon..

use max232

that's an rs232 transceiver, not a switching converter and although it uses a charge pump to get higher voltages, it's not much current.

but its cheap and can do the task , it can switch the 5V to 12V

ahmed. I looked up the TI version of the Max232, the output resistance is 300 ohms and the short circuit current is only 10ma's. If he's looking to just convert a very low current signal it'll work, totally useless for all but micro power applications though

everything

its ok people... i found out how to do it already.. thanks so much in reply my humble thread.. =)
