I have a thermo-electric heat-pump that I need to supply power to.
I have a small op-amp circuit that conditions a control signal from
our temperature controller.  I would like to know if there is a way
that I can 'super-charge' the output of the op-amp to provide 0 to 5
amps at 0 to 3.5 volts.  This project is at the experimental level at this
point so I am not ready to shell out the bucks for a programmable power
supply.  If someone could point me to an application note or such, that
would be great.

Any help would be appreciated.
