4.5 Load Transients
Figure 4 and Figure 5 show the TPS55340EVM-147 response to load transients. The current step is from
25% to 75% of maximum rated load at a 6V input and a 18V input respectively. The current step slew rate
is 10 mA/µs. Total peak-to-peak voltage variation is as shown, including ripple and noise on the output.
