To verify the calculations for Load 1, lab measurements were taken. With the Load 1 profile, the switch is turned off in Figure 4-6 to measure the demagnetization energy.
The peak power is 18 W and the demagnetization time TDEMAG can be seen as 1.3 ms. The demagnetization energy is calculated in Equation 59.
The calculated value is 15.67 mJ so the measured value is close but not exact due to variations in the inductance value and approximations in the equation derivations. It can be shown from this example that the TPS4H160-Q1 can safely demagnetize this load as shown in the calculations.
