Hi sirs,
From the application report page 8, http://www.ti.com/lit/an/spra953c/spra953c.pdf
We learned ΨJT varies with both board construction and air flow conditions as shown in Table 3. The values in Table 3 were obtained through modeling.
However, what are the conditions of PCB type and air flow that we got the thermal metric shown in TPS53353 datasheet? Thanks!
From the application report page 9:

Best regards,
