Figure 25: Input reflected ripple current, i s , through a 10
inductor at nominal input voltage and rated load current (5 mA/div).
1.8V and 3.3V outputs at 50% rated load current. (see Fig. 23)
Figure 27: Output voltage vs. load current showing typical current limit
curves and converter shutdown points for the 1.8V output. 3.3V load is
at 0A.
Figure 29: Load current for 1.8V output (20A/div) as a function of time
when the converter attempts to turn on into a 10 m short circuit. Top
trace is an expansion of the on-time portion of the bottom trace.
