Figure 13: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 5µH source impedance and 47µF
electrolytic capacitor (500mA/div). See Figure 12.
Figure 15: Output voltage ripple at nominal input voltage and rated
load current (50mV/div). Load capacitance: 1µF ceramic capacitor and
15µF tantalum capacitor. Bandwidth: 20MHz. See Figure 12.
Figure 14: Input reflected ripple current, is, through a 5 µH source
inductor at nominal input voltage and rated load current (10mA/div).
See Figure 12.
