Load Transient Response
The TPS54329EEVM-056 response to load transient is shown in
. The current step is from 1 A to
2 A. Total peak-to-peak voltage variation is as shown.
Figure 5. TPS54329EEVM-056 Load Transient Response, 1-A to 2-A Step
The TPS54329EEVM-056 response to load transient during Eco-mode
™
operation is shown in
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
