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

(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 9: Output voltage response to step-change in load

current (75%-50%-75% of Io, max; di/dt = 1A/µs). Load cap:

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 (LTEST) of 12 µH. Capacitor Cs offset

possible battery impedance. Measure current as shown above

current and nominal input voltage with 12µH source impedance

and 33µF electrolytic capacitor (200 mA/div, 2us/div)
