Figure 1: Efficiency at nominal output voltage vs. load current for
minimum, nominal, and maximum input voltage at 25
Figure 3: Encased converter (without heatsink) max. output power derating vs.
ambient air temperature for airflow rates of 100 LFM through 400 LFM. Air flows
across the converter from pin 3 to pin 1 (nominal input voltage).
