ELECTRICAL CHARACTERISTICS CURVES

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

current (75%-50%-75% of Io, max; di/dt = 2.5A/µs). Load cap:

330µF, 35m

Ω ESR solid electrolytic capacitor and 1µF ceramic

capacitor. Top Trace: Vout (100mV/div, 200us/div), Bottom

Trace: I out (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.

for Input Terminal Ripple Current and Input Reflected Ripple

Current.

Note: Measured input reflected-ripple current with a simulated

possible battery impedance. Measure current as shown above
