Figure 6-2 shows the test setup for measuring the rise time of the TPS22999. Do note the JP1 jumper is depopulated so the ON pin can be applied independently of VIN. Apply a square wave to the ON pin of the switch using a function generator and apply a voltage to the VIN terminal using a power supply. Observe the waveform at VOUT Sense with an oscilloscope to measure the slew rate and rise time of the switch with a given input voltage.
