ELECTRICAL CHARACTERISTICS CURVES

Figure 8: Output voltage response to step-change in load

current (50%-75%-50% of Imax; dI/dt = 0.1A/Âµs).Vin=48V. Load

cap: 10ÂµF, tantalum capacitor and 1ÂµF 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/Âµs). Load cap:

470ÂµF, 35mâ¦ ESR solid electrolytic capacitor and 1ÂµF 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.

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 ÂµH. Capacitor Cs offset

possible battery impedance. Measure current as shown above.
