Ambient Air Temperature (ºC)
Figure 7: Maximum output power derating curves vs. ambient air tem-
perature for airflow rates of 100 LFM through 400 LFM with air flowing
across the converter from pin input to output (nominal input voltage).
Figure 8: Thermal plot of converter at 27.4 amp load current (90.42W)
with 70°C air flowing at the rate of 200 LFM. Air is flowing across the
converter from input to output (nominal input voltage).
Figure 9: Turn-on transient at full load (resistive load) (5 ms/div). Load cap:
10uF, 100 mΩ ESR tantalum capacitor and 1uF ceramic capacitor. Input
voltage pre-applied. Ch 1: Vout (1V/div), Ch 2: ON/OFF input (5V/div).
Figure 10: Turn-on transient at zero load (10 ms/div). Load cap: 10uF,
100 mΩ ESR tantalum capacitor and 1uF ceramic capacitor. Ch 1: Vout
(1V/div), Ch 2: ON/OFF input (5V/div).
Figure 11: Output voltage response to step-change in load current (50%-
75%-50% of Iout(max); dI/dt = 0.1A/µs). Load cap: 10µF, 100 mΩ ESR tan-
talum cap and 1µF ceramic cap. Ch 1: Vout (50mV/div), Ch 2: Iout (10A/div).
Figure 12: Output voltage response to step-change in load current (50%-
75%-50% of Iout(max): dI/dt = 1A/µs). Load cap: 470µF, 30 mΩ ESR tanta-
lum cap and 1µF ceramic cap. Ch 1: Vout (50mV/div), Ch 2: Iout (10A/div).
