Calculating SOA Temperature:
(Figure 3) SOA temperature adjustment for input voltage ? -1.0oC
(Figure 5) SOA temperature adjustment for output inductor ? 0.95oC
(Figure 6) SOA temperature adjustment for switch frequency ? -1.5oC
T X axis intercept adjustment ? -1.0oC + 0.95oC – 1.5oC ? -1.55oC
Assuming T PCB = 90oC & T CASE = 110oC, the following example shows how the SOA current is
adjusted for T X decrease of 4.5oC.

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 53.5A.
