Figure 7: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 5 A/μ s; 1 ms/div). Load cap: 1uF ceramic and 10uF
Tantalum. Top trace: Vout (500 mV/div). Bottom trace: Iout (35 A/div)..
Figure 8: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max): dI/dt = 5 A/μ s; 1 ms/div). Load cap: 470 μF electrolitic
capacitor. Top trace: Vout (500 mV/div). Bottom trace: Iout (35 A/div).
Figure 9: Test set-up diagram showing measurement points for Input Terminal
Ripple Current (Figure 10), Input Reflected Ripple Current (Figure 11) and
Output Voltage Ripple (Figure 12).
Figure 10: Input Terminal Ripple Current, ic, at full rated output current and
nominal input voltage with 4.7 μH source impedance and 100 μF electrolytic
capacitor (50 mA/div; 2 μs/div). See Figure 9.
Figure 11: Input reflected ripple current, is, through a 4.7 μH source inductor,
using a 220 μF input capacitor, at nominal input voltage and rated load current
(20 mA/div; 2 μs/div). See Figure 9.
Figure 12: Output voltage ripple at nominal input voltage and rated load current
(20 mV/div; 4 μs/div). Load capacitance: 1 μF ceramic capacitor and 10 μF
tantalum capacitor. Bandwidth: 20 MHz. See Figure 9.
