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 (50mV/div,200us/div), Bottom Trace: Iout (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:
470µF, 35m
ESR solid electrolytic capacitor and 1µF ceramic
capacitor. Top Trace: Vout (50mV/div,,200us/div), Bottom
Trace: Iout (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 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
