Do you have safe operating area graph at TPS54527?

Coustomer spec is below

Vin:12V(min),13V(typ),14V(max)

Vout:3.32V

Iout:4.1A

Because my coustomer worried about that Ploss more than 2W.

there is not an SOA curve for TPS54527. If you compare to TPS54627, you will see that for 5 A case, the SOA extends all the way to the max recommended Ta of 85 C. So if a SOA curve was included in TPS54527, it would just be a straight line at 5 A from -40 C to +85 C.
