rcd snubber

Hi,

could you please help me with a RCD snubber?
I need it to limit the drain spike voltage in a boost converter.

How design? Do you have any AN or doc?

I already read this from unitrode:

Thanks!

snubber boost converter

I don't see a meaningful application of a snubber in a standard boost converter circuit. Also no spike voltage should exist here, because it's directly cut by the output diode. Today's MOSFET have built-in zener protection and can handle voltage spikes without additional circuits.
