Figure 14: Input Terminal Ripple Current, ic, at full rated output current and
nominal input voltage with 10H source impedance and 47F electrolytic
capacitor (200 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 10 H source inductor at
nominal input voltage and rated load current (5 mA/div). See Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated load current
(50 mV/div). Load capacitance: 1F ceramic capacitor and 10F tantalum
capacitor. Bandwidth: 20 MHz. See Figure 13.

and converter shutdown points.
Figure 18: Load current (20A/div) as a function of time when the converter
attempts to turn on into a 10 m short circuit. Top trace (2.0ms/div) is an
expansion of the on-time portion of the bottom trace.
