I have a 0-5V variable PWM signal that I need to convert to a 0 - 12V output signal relative to the PWM input change for a tachometer.
How can I accomplish this?

It depends on the frequency involved and the input impedance of your low pass filter.

Something like the attached BD2301G would probably work in most cases

Replace the MOSFET with your low pass filter.
