OUTPUT LOAD STEP RESPONSE
The load step response of DC1409A is very good even though relatively small amount of output
capacitance is present at the output. If higher load steps need to be handled more output capaci-
tance can be added in order to keep the voltage transients at the desired level. The load step tran-
sients are shown in Figure 5 and Figure 6. Also, note that load step response even from 0% load is
excellent thanks to synchronous rectification.
