If you only need 9 steps in your 2Khz PWM (10% each step), then Mikes idea will work just fine.

If you want 80 steps between 10-90%, I think you can use SSPWM ...

The article lists lower maximum frequencies because it can't get 1% resolution so close to the start and end points. But if you only need 10-90%, it should be OK.

If you plan on using it, I will test it to make sure.
Since this thread was from last February, I have doubts.
