10.2.1 Theta JA versus PCB Area
The amount of PCB copper affects the thermal performance of the device. Figure 10-3 shows the effects of copper area on the junction-to-ambient thermal resistance (RθJA) of the TPSM265R1. The junction-to-ambient thermal resistance is plotted for a 4-layer PCB with an area from 0.5 cm2 to 39 cm2.
To determine the required copper area for an application:
- Determine the maximum power dissipation of the device in the application by referencing the power dissipation graphs in Section 6.6 to Section 6.10.
- Calculate the maximum θJA using Equation 9 and the maximum ambient temperature of the application.
Equation 9.
- Reference Figure 10-3 to determine the minimum required PCB area for the application conditions.
