Figure 1: Efficiency at nominal output voltage vs. load current for minimum,
nominal, and maximum input voltage at 25°C.
Figure 2: Efficiency at nominal output voltage and 60% rated power vs.
airflow rate for ambient air temperatures of 25°C, 40°C, and 55°C (nominal
input voltage).
Figure 3: Power dissipation at nominal output voltage vs. load current for
minimum, nominal, and maximum input voltage at 25°C.
Figure 4: Power dissipation at nominal output voltage and 60% rated power
vs. airflow rate for ambient air temperatures of 25°C, 40°C, and 55°C
(nominal input voltage).
Figure 5: Maximum output power derating curves vs. ambient air temperature
for airflow rates of 100 LFM through 400 LFM with air flowing from pin 3 to
pin 1 (nominal input voltage).
Figure 6: Thermal plot of converter at 15.0 amp load current (49.5W) with
55°C air flowing at the rate of 200 LFM. Air is flowing from pin 3 to pin 1
(nominal input voltage).
