Thermal Derating
Load current vs. ambient temperature and airflow
rates are given in Figs. x.1 to x.2 for maximum
temperature of 110 °C. Ambient temperature was
varied between 25 °C and 85 °C, with airflow rates
from 30 to 500 LFM (0.15 m/s to 2.5 m/s), and
vertical and horizontal converter mountings. The
airflow during the testing is parallel to the long axis of
the converter, going from pin 1 and pin 6 to pins 2–5.
For each set of conditions, the maximum load
current is defined as the lowest of:
(i) The output current at which any MOSFET
temperature
specified temperature (110 °C) as indicated by the
thermographic image, or
(ii) The maximum current rating of the converter
(10 A)
During normal operation, derating curves with
maximum FET temperature less than or equal to
110 °C should not be exceeded. Temperature on the
PCB at the thermocouple location shown in Fig. D
should not exceed 110 °C in order to operate inside
the derating curves.
Efficiency
Figure x.3 shows the efficiency vs. load current plot
for ambient temperature of 25 ºC, airflow rate of
200 LFM (1 m/s) and input voltages of 9.6 V, 12 V,
and 14 V.
Power Dissipation
Fig. x.4 shows the power dissipation vs. load current
plot for Ta = 25 ºC, airflow rate of 200 LFM (1 m/s)
with vertical mounting and input voltages of 9.6 V,
12 V, and 14 V.

Ripple and Noise
The output voltage ripple waveform is measured at
full rated load current. Note that all output voltage
waveforms are measured across a 1 μF ceramic
capacitor.
The output voltage ripple and input reflected ripple
current waveforms are obtained using the test setup
shown in Fig. E.

and output voltage ripple.
