Figure 7: Maximum output power derating curves at 55°C vs. airflow
rates of 100 through 400 LFM. Curve shows available current for 1.8V
rail on y axis and available current for 3.3V rail on x axis. (nom. Vin)
Figure 8: Thermal plot of converter at 15A load on 1.8V ouput and 15A
load on 3.3V output with 55°C air flowing at 200 LFM. Air flow across
the converter is from pin 1 to pin 3 (nominal input voltage).
Figure 9: Maximum output power derating curves at 70°C vs. airflow
rates of 100 through 400 LFM. Curve shows available current for 1.8V
rail on y axis and available current for 3.3V rail on x axis. (nom. Vin)
Figure 10: . Thermal plot of converter at 15A load on 1.8V ouput and
12.5A load on 3.3V output with 70°C air flowing at 200 LFM. Air flow
across the converter is from pin 1 to pin 3 (nominal input voltage).
