For correct measurement results, the sense pins should be connected directly to the power pins.
Dynamic Response:
Positive Load Step: dIo = 25 A
Ch1: V(Uo), 50 mV/div. Ch3: Io, 20 A/div.

s/div.

Negative Load Step: dIo = 25 A
Ch1: V(Uo), 50 mV/div. Ch3: Io, 20 A/div.

Figure 12:
TXS100ZD Load Step 100 A to 75 A
@ TA = 25 °C, Ui = Ui nom
The apparent overshoot in the output voltage load step recovery is due to an overshoot in the current drawn
by the electronic load. The dynamic performance of the converter at different dIo/dt and different capacitive
loads can be estimated with an interactive tool on the TXS CD ROM.
