5 / 13 page DS_Q48SQ12018_08092013 5 ELECTRICAL CHARACTERISTICS CURVES Figure 8: Output voltage response to step-change in load current (75%-50% of Io, max; di/dt = 0.1A/µs). Load cap: 100uF Al-Electrolytic capacitor, 10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout; 200mV/div; Bottom Trace: output current: 5A/div, Time: 200us/div Figure 9: Output voltage response to step-change in load current (50%-75% of Io, max; di/dt = 0.1A/µs). Load cap: 100uF Al-Electrolytic capacitor, 10µF tantalum capacitor and 1µF ceramic capacitor. Top Trace: Vout; 200mV/div; Bottom Trace: output current: 5A/div, Time: 200us/div 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. Figure 11: Input Terminal Ripple Current, ic, at full rated output current and nominal input voltage with 12µH source impedance and 33µF electrolytic capacitor (200 mA/div,2us/div). |
