Load Current (A)
Figure 1: Efficiency at nominal output voltage vs. load current for
minimum, nominal, and maximum input voltage at 25°C.
Input: 35-75 V
Output: 12 V
Current: 25 A (300W)
Package: Quarter-brick
Figure 2: Power dissipation at nominal output voltage vs. load current
for minimum, nominal, and maximum input voltage at 25°C.
Figure 3: Maximum output power derating curves vs. ambient air tem-
perature for airflow rates of 100 LFM through 400 LFM with air flow-
ing across the converter from pin 1 to pin 3 (nominal input voltage).
Figure 4: Thermal plot of converter at 24A load current (288W) with
55°C air flowing at the rate of 200 LFM. Air is flowing across the con-
verter sideways from pin 1 to pin 3 (nominal input voltage).
Figure 5: Maximum output power derating curves vs. ambient air tem-
perature for airflow rates of 100 LFM through 400 LFM with air flow-
ing lengthwise from input to output (nominal input voltage).
Figure 6: Thermal plot of converter at 23A load current (276W) with
55°C air flowing at the rate of 200 LFM. Air is flowing across the con-
verter from input to output (nominal input voltage).
