8.2.4.5 Device Junction Temperature Estimation
For an ambient temperature of TA and total power dissipation (PTOT), the junction temperature (TJ) is calculated
as shown in the following equation. TJ = TA + (PTOT x RθJA)
Considering a JEDEC standard 4-layer PCB, the junction-to-ambient thermal resistance (RθJA) is 30.9 °C/W for
the HTSSOP package and 40.7 °C/W for the VQFN package.
Assuming 25°C ambient temperature, the junction temperature for the HTSSOP package is calculated as shown
