Dear Darrel, Steve,

Thanks again for your info and suggestions!
It maybe good for me to have a look at the problem from the other side; i.e.
the PWM requirements for my dimming device.
If I can make a setup accepting PWM over the full 5ms for a 0-100% light control it would be perfect to and Multi-SPWM could do the job.

I'll keep you informed.
