Ambient Air Temperature(°C)
Figure 7: Thermal Derating (max output current 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 Image of converter at 8.3 amp load current (415W) 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 (20V/div). Bottom Trace: ON/OFF
input(10V/div)
Figure 10: Turn-on Transient at zero load (10 ms/div). Top Trace: Vout (20V/
div). Bottom Trace: ON/OFF input (10V/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: 1µF ceramic output
capacitance. Top trace: Vout (2V/div). Bottom trace: Iout (5A/div).
Figure 12: Output Voltage Response to Step-Change in Load Current (50%-
75%-50% of Iout(max): dI/dt = 2A/µs). Load cap: 100µF electrolytic output
capacitance. Top trace: Vout (2V/div). Bottom trace: Iout (5A/div).
