Ambient Air Temperature(°C)
Figure 7: Maximum output power derating curves vs. ambient air temperature
for airflow rates of 100 LFM through 400 LFM with air flowing lenghtwise
from input to output (nominal input voltage).
Figure 8: Thermal plot of converter at 4.0 amp load current (48W) with 55°C
air flowing at the rate of 200 LFM. Air is flowing across the converter from
input to output (nominal input voltage).
Figure 9: Turn-on transient at full load (resistive load) (10 ms/div). Input
voltage pre-applied. Top Trace: Vout (5V/div). Bottom Trace: ON/OFF
input(5V/div)
Figure 10: Turn-on transient at zero load (10 ms/div). Top Trace: Vout (5V/
div). Bottom Trace: ON/OFF input (5V/div)
Figure 11: Output voltage response to step-change in load current (50%-
75%-50% of Iout(max); dI/dt = 0.1A/µs). Load cap: 100µF electrolytic output
capacitance. Top trace: Vout (200mV/div). Bottom trace: Iout (1A/div).
Figure 12: Output voltage response to step-change in load current (50%-
75%-50% of Iout(max): dI/dt = 2A/µs). Load cap: 330µF electrolytic output
capacitance. Top trace: Vout (200mV/div). Bottom trace: Iout (1A/div).
