You need a circuit like this, it will smooth the PWM and then give it a boost with the FET. Just replace your load where it says FAN.

If you don't want a smooth voltage and PWM will do then use this circuit:-


Thanks, Grumpy Mike. That did the trick! I wired up the second circuit, and it looks like it will work. Unfortunately, I cannot test the circuit on the device itself for a couple of weeks. I'll post back then with final results.
