Acknowledging that the PWM runs at 62.5MHz maximum, you of coarse have limitations in frequency range and duty cycle range. But, different from off-the-shelf chips, you can play with them. In the end I think I will end up with a 62.5MHz/200=312kHz PWM, and as close as possible 49% and 51% duty cycle, but it could also end up in 48/52%. Many tests to be performed. Especially the EMI/EMC tests. I may even have to slow down the switching FET's to meet my target.
