Figures
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 (no heatsink) vs. ambient air
temperature for airflow rates of 0 LFM through 400 LFM with air flowing from input
to output (nominal input voltage).
Figure 6: Output voltage vs. load current showing typical current limit curves and
converter shutdown points.
