for minimum, nominal, and maximum input voltage at 25°C.
Figure 3: Maximum output power derating curves vs. ambient air temperature
for airflow rates of 100 LFM through 400 LFM with air flowing across the
converter from pin 1 to pin 3 (nominal input voltage).
Figure 4: Thermal plot of converter at 24A load current (288W) with 55°C air
flowing at the rate of 200 LFM. Air is flowing across the converter sideways from
pin 1 to pin 3 (nominal input voltage).
Semiconductor junction temperature is
within 1°C of surface temperature
Figure 5: Maximum output power derating curves vs. ambient air temperature
for airflow rates of 100 LFM through 400 LFM with air flowing from from input
to output (nominal input voltage).
Figure 6: Thermal plot of converter at 23A load current (276W) with 55°C air
flowing at the rate of 200 LFM. Air is flowing across the converter from input to
output (nominal input voltage).
