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 mΩESR tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout (50mV/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 mΩESR tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout (50mV/div), Bottom Trace: Iout 5A/div).
Figure 8: Test set-up diagram showing measurement points 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 possible battery impedance.
