Example 2) Adjusting for SOA Temperature:

(Fig. 3) Normalized SOA Temperature for input voltage ≈ -0.8°C

(Fig. 4) Normalized SOA Temperature for output voltage ≈ 8.4°C

(Fig. 5) Normalized SOA Temperature for frequency ≈ -1.8°C

(Fig. 6) Normalized SOA Temperature for inductor value ≈ 0.75°C

T_Xaxis intercept temp adjustment = - 0.8°C + 8.4°C - 1.8°C + 0.75°C ≈ 6.6°C

Assuming T_CASE= 100°C & T_PCB= 90°C:

The following example shows how the SOA current is adjusted for a T_Xincrease of 6.6°C.
