ronv, thanks for answering my post.
I have 70ns deadtime, so at 800kHz, which is the frequency I will use, the deadtime is 11.2% of the switching cycle. Would this be considered "short"?
EDIT: Correction! The 70ns is referred to as "non overlap time" in the datasheet and happens 2 times every cycle. So at 800kHz the non overlap time is 22.4% of the switching cycle.
I will try to follow the guide I linked to, and see where that takes me. I guess the process is the same whether I use 1 or 2 RC snubbers? I'll make room on the PCB for both types and see what I can figure out.
