    This is something VERY easy to get with a PC power supply and one pot or 
one resistor.

    ALL PC power supplies uses a (or a variant of) TL494. Change the divider 
network (two resistors) on pin 1, connected to 5V and you can raise it to 8V 
and 12V will have around 18V

    Simple, easy and stable.
