Figure 14: Input Terminal Ripple Current, ic, at full rated output cur- rent and nominal input voltage with 10µH source impedance and 47µF electrolytic capacitor (200 mA/div). (See Figure 13) Figure 15: Input reflected ripple current, is, through a 10 µH source inductor at nominal input voltage and rated load current (5 mA/div). (See Figure 13) Figure 16: Output voltage ripple at nominal input voltage and rated load current (100 mV/div). Load capacitance: 1µF ceramic capacitor and 15µF tantalum capacitor. Bandwidth: 20 MHz.
