Figure 17: Max output power derating curves vs. air temp for 0 to 400 LFM, pin
3 to pin 1. 70% load (8.5A) on 3.3V output and 30% load (2.4A) on 5.0V output.
At derating points, 3.3V output decreases while 5.0V output remains unchanged.
Figure 18: Thermal plot of converter at 8.5 amp load on 3.3V ouput and
2.4 amp load on 5.0V output with 55°C air flowing at 200 LFM. Air
flow across the converter is from pin 3 to pin 1 (nominal input voltage).

Figure 13: Maximum output power-derating curves vs. ambient air tem-
perature for airflow rates of 0 to 400 LFM, air flowing from pin 3 to pin
1. Full load (8A) on 5.0V output and no load on 3.3V output.

no load on 3.3V output with 55°C air flowing at 200 LFM. Air flow
across the converter is from pin 3 to pin 1 (nominal input voltage)
Figure 15: Max output power-derating curves vs. air temp for 0 - 400 LFM, pin
3 to pin 1. 50% load (6A) on 3.3V output and 50% load (4A) on 5.0V output. At
derating points, 3.3V output decreases while 5.0V output remains unchanged.
