ELECTRICAL CHARACTERISTICS CURVES

Figure5: Turn-on transient at zero load current (1 ms/div). Top

Trace: Vout (500mV/div); Bottom Trace: ON/OFF Control

(5V/div).

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

current (50%-75% of Io, max; di/dt = 0.1A/µs). Load cap: 10µF,

100 mΩESR tantalum capacitor and 1µF ceramic capacitor.

Top Trace: Vout (20mV/div), Bottom Trace: Iout (5A/div).

Figure 7: Output voltage response to step-change in load

current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap:

10µF,

100 mΩESR tantalum capacitor and 1µF

ceramic capacitor.

Top Trace: Vout (20mV/div), Bottom

for Input Reflected Ripple Current (Figure 9).

Note: Measured input reflected-ripple current with a simulated

source Inductance (LTEST) of 12 µH. Capacitor Cs offset
