Figure 1: Efficiency at nominal output voltage vs. load current for minimum,
nominal, and maximum input voltage at 25°C.
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 input to output (nominal input voltage).
Figure 5: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max); dI/dt = 0.1 A/µs). Load cap: 1 µF Ceramic capacitor. Ch 1:
Vout, Ch 2: Iout (2A/div).
