Dears,
Regarding GaN daughter card and as attached here the answer from Riccardo
We can’t see the relation between current limitation and the limit placed by layout slew rate dv/dt, please explain more.

Hi,
the power switch need to dissipate the sequent power loss terms:
Slew rate is giving you a direct relation with the switching losses. If you switch faster you are going to achieve lower switching losses (contemporary time presence of current and voltage is smaller). If you switch with a speed from 30 kV/us to 100 kV/us you are going to achieve 70% of switching loss reduction.
An example:
Thanks for your attention
