Are there any special considerations for this large of a step-down with TPS51216? Are there any reference designs or design tools to help with this?
I did find PMP6807 and PMP5783.1
Thanks,

Please be careful in the height of high frequency ringing at the switch node not to go over the recommended operating condition, 28V. When it is larger than 28V, try resistance in series to the boost capacitor and/or snubber.
As for the design tool, following one may help.
