ELECTRICAL CHARACTERISTICS CURVES
Figure 8: Output voltage response to step-change in load current
(50%-75%-50% of Io, max; di/dt = 0.1A/µs; Vin is 24V). Load cap:
10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace:
Vout (0.2V/div, 100us/div), Bottom Trace:Iout (10A/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
TEST
) of 12 μH. Capacitor Cs offset
possible battery impedance. Measure current as shown above.
