Figure 14: Input Terminal Ripple Current, ic, at full rated output current and
nominal input voltage with 10H source impedance and 47F electrolytic
capacitor (200 mA/div). (See Figure 13)
Figure 15: Input Reflected Ripple Current, is, through a 10 H 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 (20 mV/div). Load capacitance: 1F ceramic capacitor and 15F
tantalum capacitor. Bandwidth: 20 MHz. (See Figure 13)
