    Hey guys, I need some help. 

    Do you know how to convert fixed voltage to variable?

    for example 12V to 19,5V

    Hi Mick,

    There are somany different methods. You can use a simple variable resistor, connect it across the supply and you can vary the voltage at the variable pin by rotating the screw.

    You can generate any voltage from 0 to 12 on the variable pin if you are using a 12V power supply.

     

    I guess you want to know something more, is that so?

    Ofcorse it is not very easy to generate 19 volt from a 12V supply.
