Calculating SOA Temperature:
(Figure 3)
(Figure 4)
(Figure 5)
(Figure 6)
(Figure 7)
SOA temperature adjustment for input voltage ≈ -0.5oC
SOA temperature adjustment for output voltage ≈ 5.5oC
SOA temperature adjustment for drive voltage (V DD ) ≈ -0.8 oC
SOA temperature adjustment for output inductor ≈ 0.6 oC
SOA temperature adjustment for switch frequency ≈ -1.9 oC
TX axis intercept adjustment ≈ -0.5 oC + 5.5 oC - 0.8 oC + 0.6 oC - 1.9 oC ≈ 2.9 oC
Assuming T PCB = 95oC & T CASE = 110oC
The following example shows how the SOA current is adjusted for T X increase of 2.9oC

PCB Temperature (oC)
1. Draw a line from Case Temperature axis to the PCB Temperature axis.
2. Draw a vertical line from the T X axis intercept to the SOA curve.
3. Draw a horizontal line from the intersection of the vertical line with the SOA curve to
the Y-axis (Output Current). The point at which the horizontal line meets the Y-axis is
the SOA continuous current.
4. Draw a new vertical line from the T X axis by adding or subtracting the SOA adjustment
temperature from the original T X intercept point.
5. Draw a horizontal line from the intersection of the new vertical line with the SOA curve
to the Y-axis (Output Current). The point at which the horizontal line meets the Y-axis
is the new SOA continuous current.
The SOA adjustment indicates the part is still allowed to run at a continuous current of 30A.
