2.7 Load Transient Response
The TPS54426EVM-608 response to load transient is shown in Figure 5. The current step is from 500 mA
to 1.5 A (25% to 75% of rated load). Total peak-to-peak output voltage variation is as shown.

2.8 Output Voltage Ripple
The TPS54426EVM-608 output voltage ripple is shown in Figure 6. The output current is the rated full load
of 2A.
