In cases where the board temperature is known, the thermal

characterization parameter (ΨJB) can be used to estimate the

junction temperature rise. The maximum junction temperature

(TJ) is calculated from the board temperature (TB) and power

dissipation (PD) using the following formula:

TJ = TB + (PD × ΨJB)

(7)

Figure 40 through Figure 43 show the junction temperature

calculations for the different board temperatures, load currents,

VIN to VOUT differentials, and areas of PCB copper.
