ambient air temperature for airflow rates of 100 LFM through 400 LFM. Air flows
across the converter from input to output (nominal input voltage).
Figure 5: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.1 A/µs). Load cap: 15 µF Tantalum + 1 µF Ceramic
capacitor. Ch 1: Vout (200 mV/div), Ch 2: Iout (25 A/div).
Figure 6: Output voltage response to step-change in input voltage
(500 V/ms). Load cap: 100 µF, electrolytic output capacitance.
Ch 1: Vout (500 mV/div), Ch 2: Vin (50 V/div).
