For the test in Figure 8-2, 40 V was applied to the input and 10 A was drawn from the output. Ringing can be present on the switching node if the converter is run in discontinuous conduction mode rather than the continuous conduction mode the design was run with.
For tests shown in and , 40 V was applied to the input and a load step was applied to the output. The load step applied was from 0 A to 10 A and 10 A to 0 A. Note that those currents do not include the 0.1-A pre-load. The curves show that the stability of the design due to the lack of ringing during the load step.
