Figure 19: Input reflected ripple current, is, through a 10 μH source inductor at

nominal input voltage and rated load current (10mA/div). See Figure 17.

Figure 20: Output voltage ripple at nominal input voltage and rated load current

(20mV/div). Load capacitance: 1μF ceramic capacitor and 10μF tantalum

capacitor. Bandwidth: 20MHz. See Figure 17.

Figure 21: Output voltage vs. load current showing typical current limit curves

and converter shutdown points.

Figure 22: Load current (5A/div) as a function of time when the converter

attempts to turn on into a 10 mW short circuit. Top trace (40ms/div) is an

expansion of the on-time portion of the bottom trace.
