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: I out (3.75A/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: 330µF, 35mΩ ESR solid electrolytic capacitor and 1µF ceramic capacitor. Top Trace: Vout (100mV/div, 200us/div), Bottom Trace: I out (3.75A/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 above
