Figure 8: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF,
tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout;
100mV/div; Bottom Trace: output current: 15A/div, Time:
200us/div

Figure 10: Test set-up diagram showing measurement points
for Input Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (LTEST) of 12 μH. Capacitor Cs offset
possible battery impedance. Measure current as shown above.
Figure 11: Input Terminal Ripple Current, ic, at full rated output
current and nominal input voltage with 12µH source impedance
and 33µF electrolytic capacitor (200 mA/div，2us/div).
