Ambient Air Temperature (°C)
Figure 4: Encased converter (with 1/4” 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).
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 and 15 µF tantalum
capacitors. Ch 1: Vout (500 mV/div), Ch 2: Iout (10 A/div).
Figure 6: Output voltage response to step-change in input voltage
(1000 V/ms). Load cap: 100 µF, electrolytic output capacitance. Ch 1: Vout
(200 mV/div), Ch 2: Vin (50 V/div).
