4.6 Load Transient Response
The TPS54229EEVM-056 response to load transient is shown in Figure 5. The current step is from 0.5 A
to 1.5 A. Total peak-to-peak voltage variation is as shown.
Figure 5. TPS54229EEVM-056 Load Transient Response
The TPS54229EEVM-056 response to light-load transient is shown in Figure 6. In this test, the
TPS54229E is operating in Eco-mode™ at 10-mA load and a 1-A step load is applied. Total peak-to-peak
voltage variation is as shown.
