RθJC(top)Junction-to-case (top) thermal resistance41.7°C/W
RθJBJunction-to-board thermal resistance20.9°C/W
ΨJTJunction-to-top characterization parameter1.0°C/W
ΨJBJunction-to-board characterization parameter20.8°C/W
RθJC(EVM)(3)Junction-to-ambient thermal resistance on TPS562212EVM70°C/W
For more information about traditional and new thermal metrics, see the Semiconductor and IC Package Thermal Metrics application report, SPRA953
The value of RθJA given in this table is only valid for comparison with other packages and can not be used for design purposes. These values were simulated on a standard JEDEC board. They do not represent the performance obtained in an actual application.
The real RθJA  on the TPS562212EVM is about 70℃/W, test condition: VIN = 12 V, VOUT = 5 V, IOUT = 2 A, T= 25℃.
