Ambient Air Temperature (°C)
Figure 7: Maximum output power-derating curves vs. ambient air tem-
perature for airflow rates of 100 LFM through 400 LFM with air flow-
ing from input to output (nominal input voltage).
Figure 8: Thermal plot of converter at 3 amp load current (72W) with
55°C air flowing at the rate of 200 LFM. Air is flowing across the con-
verter from input to output (nominal input voltage).
Figure 9: Turn-on transient at full load (resistive load) (5 ms/div).
Input voltage pre-applied. Ch 1: Vout (10V/div). Ch 2: ON/OFF input
(5V/div)
Figure 10: Turn-on transient at zero load (5 ms/div). Ch 1: Vout
(10V/div). Ch 2: 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/µ s). Load cap: 15µ F, 100 mW ESR tan-
talum cap and 1µ F ceramic cap. Ch 1: Vout (500mV/div), Ch 2: Iout (1A/div).
Figure 12: Output voltage response to step-change in load current (50%-75%-
50% of Iout(max): dI/dt = 1A/µ s). Load cap: 90µ F, 15µ F, 100 mW ESR tanta-
lum cap and 1µ F ceramic cap. Ch 1: Vout (500mV/div), Ch 2: Iout (1A/div).
