Figure 8: Output voltage response to step-change in load
current (75%-50% of Io, max; di/dt = 1A/10µS). Load cap:
330µF aluminum,10uF Low ESR capacitor and 1µF ceramic
capacitor. Top Trace: Vout (100mV/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.

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.
