Figure 8: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 0.1A/µs). Load cap:
10µF, tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (100mV/div, 200us/div), Bottom Trace: I out (3.75A/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 9: Output voltage response to step-change in load
current (75%-50%-75% of Io, max; di/dt = 1A/µs). Load cap:
330µF, 35m
Ω ESR solid electrolytic capacitor and 1µF ceramic
capacitor. Top Trace: Vout (100mV/div, 200us/div), Bottom
Trace: I out (3.75A/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.

for Input Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (L
