Figure 8: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 0.1A/µs, Vin=48V). Load
cap:300µF, electrolytic capacitor ; 10µF, tantalum capacitor and
1µF ceramic capacitor. Top Trace: Vout (200mV/div, 200us/div);
Bottom Trace: Io (10A/div, 200us/div). Scope measurement
should be made using a BNC cable (length shorter than 20
inches). Position the load between 51 mm to 76 mm (2 inches
to 3 inches) from the module..

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.

current and nominal input voltage with 12µH source impedance
and 100µF electrolytic capacitor (1A/div，2us/div).
