4.6 Load Transient Response

Figure 4-5 shows the TPS54329EEVM-056 response to load transient. The current step is from 1 A to 2 A. Total peak-to-peak voltage variation is as shown.

Figure 4-6 shows the TPS54329EEVM-056 response to load transient during Eco-mode operation. The initial load current is 0.01 A, and the TPS54329E is operating in Eco-mode. The load step is to 1 A, taking the TPS54329E out of Eco-mode operation as shown in the VOUT waveform.
