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: Iout
(5A/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

470µF, 35mΩ ESR solid electrolytic capacitor and 1µF ceramic
capacitor.

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 (L_TEST) of 12 µH. Capacitor Cs offset
possible battery impedance. Measure current as shown above
