Figure 7: Maximum output power derating curves vs. ambient air tem-
perature for 1.2Vout unit. Airflow rates of 50 LFM - 400 LFM with air
flowing across the converter from pin 11 to pin 1 (Vin nom, vert mount).
Figure 8: Thermal plot of 1.2V converter at 15 amp load current with
55°C air flowing at the rate of 200 LFM. Air is flowing across the con-
