TPS55340EVM-017, 5-V to 12-V Input, 24-V Output Boost Evaluation Module
4.5 Load Transients
Figure 4 and Figure 5 show the EVM's response to load transients. The current step is from 25% to 75%
of maximum rated load at a 5-V input and a 12-V 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.
