Ripple Current (Figure 14), Input Reflected Ripple Current (Figure 15) and
Output Voltage Ripple (Figure 16).
Figure 14: Input Terminal Ripple Current, ic, at full rated output current and
nominal input voltage with 10µH source impedance and 47µF electrolytic
capacitor (100 mA/div). See Figure 13.
Figure 15: Input reflected ripple current, is, through a 10 µH source inductor,
using a 47µF electrolytic input capacitor (5mA/div). See Figure 13.
Figure 16: Output voltage ripple at nominal input voltage and rated load current
(20 mV/div). Load capacitance: 1µF ceramic capacitor and 15µF tantalum
capacitor. Bandwidth: 20 MHz. See Figure 13.
