ELECTRICAL CHARACTERISTICS CURVES
Figure 8:
Output voltage response to step-change in load
current (50%-75%-50% of Imax; dI/dt = 0.1A/μs).Vin=48V. Load
cap: 10μF, tantalum capacitor and 1μF ceramic capacitor. Top
trace: Vout (100mV/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 and
76 mm ( 2 inches and 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 (100mV/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.

for Input
Terminal Ripple Current and Input Reflected Ripple
Current.
Note: Measured input reflected-ripple current with a simulated
source Inductance (L

) of 12
μ
H. Capacitor Cs offset
possible battery impedance. Measure current as shown above.
