Figure 7: Maximum output power derating curves vs. ambient air tem-
perature for airflow rates of 0 LFM through 400 LFM with air flowing
from output to input (nominal input voltage).
Figure 8: Thermal plot of converter at 24.5 amp load current with 55°C
air flowing at the rate of 200 LFM. Air is flowing across the converter
from output to input (nominal input voltage).

Figure 11: Output voltage response to step-change in load current (50%-75%-50%
of Iout(max); dI/dt = 0.1A/s). Load cap: 15F, 450 m
ESR tantalum capacitor and
1F ceramic capacitor. Top trace: Vout (200mV/div), Bottom trace: Iout (10A/div).
