Figure 3-2 and Figure 3-3 show load transient 1 at 14 V_IN. Load transient 1 shows a step response for load step from 30 A to 60 A (Figure 3-2), followed by a load dump from 60 A to 30 A (Figure 3-3). Load change time is about 2 μs. The undershoot and overshoot for each is about 2% or 66 mV. In both images, the blue trace is V_OUT and the green trace is I_OUT, but 30-A static load is not shown.

Figure 3-4 shows the load transient at 32 V_IN. The load step response is for a load step from 0.8 A to 30.8 A, followed by load dump back to 0.8 A. The load change time is about 2 μs. Undershoot and overshoot are each about 60 mV.
