ELECTRICAL CHARACTERISTICS CURVES

Figure 6: Output voltage response to step-change in load

current (50%-25%-50% of Io, max; di/dt = 0.1A/µs). Load cap:

10µF, tantalum capacitor and 1µF ceramic capacitor. Top Trace:

Vout (200mV/div, 500us/div), Bottom Trace: I out (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 7: Output voltage response to step-change in load

current (50%-25%-50% of Io, max; di/dt = 2.5A/µs). Load cap:

10µF, tantalum capacitor and 1µF ceramic capacitor. Top Trace:

Vout (200mV/div, 500us/div), Bottom Trace: I out (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 8: 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 12µH. Capacitor Cs offset possible

battery impedance. Measure current as shown above
