not gate (inverter) ic that can source and sink 15mA

precisly so if i use 2 n channel moses then the source of one will already be at 12 volts so i will need to apply 24 volts to offset that !
the google searchs just reveal stuff that sources like 100 mA i am trying to build something that will source like 10 amps (at 24 volts) meaning a 12 v drain of 20 amps (10 per mos) this will then be restepped down to more stable values. perhaps with some gating i can create a variable output from like 3.3 to 24 volts by controlling the pulse width now that pulse modulation has been brought in by that IC or i may resign all the controll and there for resolve the simutainious on problem by macking my own control circuitry.

What do you have that draws 10A at 24V?

the rest of the circuit that will rereduce it to a stable 12 volts so that i can power a pc so go on and laugh now. but if my idea of using pulse width modulation i should be able to vary it to produce directly 12 volts alrady stable.
