DRL (SOT583)
8 PINS
RθJA (2) Junction-to-ambient thermal resistance 116.7 °C/W
RθJC(top) Junction-to-case (top) thermal resistance 41.7 °C/W
RθJB Junction-to-board thermal resistance 20.9 °C/W
ΨJT Junction-to-top characterization parameter 1.0 °C/W
ΨJB Junction-to-board characterization parameter 20.8 °C/W
RθJC(EVM) (3) Junction-to-ambient thermal resistance on TPS562211EVM 70 °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 cannot 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 TPS562211EVM is about 70℃/W, test condition: VIN = 12 V, VOUT = 5 V, IOUT = 2 A, T= 25℃.
