Figure 14: Input Terminal Ripple Current, ic, at full rated output cur-
rent and nominal input voltage with 3.3H source impedance and
100F electrolytic capacitor (500 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 3.3 H source
inductor at nominal input voltage and rated load current (20 mA/div).
See Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated
load current (20 mV/div). Load capacitance: 1F ceramic capacitor
and 10F tantalum capacitor. Bandwidth: 20 MHz. See Figure 13.
Figure 13: Test set-up diagram showing measurement points for Input
Terminal Ripple Current (Figure 14), Input Reflected Ripple Current
(Figure 15) and Output Voltage Ripple (Figure 16).
