2.6 Load Transient Response
The TPS54226EVM-539 response to load transient is shown in Figure 2-4 . 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.
VOUT = 50 mV/div (AC coupled)
IOUT = 500 mA/div, 0.5 to 1.5 A Load Step
Time = 200 s/div
