In the case where the board temperature is known, use the ΨJB

thermal characterization parameter to estimate the junction

temperature rise (see Figure 77 and Figure 78). Maximum

junction temperature (TJ) is calculated from the board tempera-

ture (TB) and power dissipation (PD) using the following

formula:

TJ = TB + (PD × ΨJB)

(5)

The typical value of ΨJB is 15.1°C/W for the 8-lead LFCSP package

and 31.3°C/W for the 8-lead SOIC package (see Table 7).
