Figure 17: Max output power derating curves vs. air temp for 100 to 400 LFM, pin 3 to
pin 1. 75% load (12A) on 1.225V output and 25% load (2A) on 2.45V output. At derating
points, 1.225V output decreases while 2.45V output remains unchanged
.
Figure 18: Thermal plot of converter at 12 amp load on 1.225V output
and 2 amp load on 2.45V output with 85°C air flowing at 200 LFM. Air
flow across the converter is from pin 3 to pin 1 (nominal input voltage).

no load on 1.225V 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 100- 400 LFM,
pin 3 to pin 1. 50% load (8A) on 1.225V output and 50% load (4A) on 2.45V
output. At derating points, 1.225V output decreases while 2.45V output remains
unchanged.
