I am looking to get some more information about the thermal metrics on PN: LM25575
I found another component (LM63610) that has the same case (HTSSOP) and included some additional thermal metrics in the datasheet. Right now I am using these properties to extrapolate a PSI JC Value for the LM25575 component. I would appreciate any comment on the validity of this technique or some advice on reaching an approximate PSI JC.

LM63610 (Component with the same case):
Thank you for your time,
