Figure 8: Output voltage response to step-change in load

current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF

tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout

(100mV/div, 50us/div), Bottom Trace: Iout (2A/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 below
