Ambient Air Temperature (^oC)
Figure 13: Maximum output power derating curves vs. ambient air tem-
perature for 3.3Vout unit at 5.0Vin. Airflow rates of 50 - 400 LFM with
air flowing across the converter from pin 11 to pin 1 (vert mount).
Semiconductor junction temperature is
within 1°C of surface temperature
Figure 14: Thermal plot of 3.3Vout converter at 5.0Vin with 15 amp
load current and 55°C air flowing at the rate of 200 LFM. Air is flow-
ing across the converter from pin 11 to pin 1 (vertical mount).
