minimized. This provides a worst-case but
consistent scenario for thermal derating purposes.
All measurements requiring airflow were made in
di/dt’s vertical and horizontal wind tunnel facilities
using
thermocouples for thermometry.
Ensuring components on the converter do not
exceed their ratings is important to maintaining
high reliability. If one anticipates operating the
converter at or close to the maximum loads
specified in the derating curves, it is prudent to
check actual operating temperatures in the
application. Thermographic imaging is preferable;
if
thermocouples
recommends the use of AWG #40 gauge
thermocouples to ensure measurement accuracy.
Careful routing of the thermocouple leads will
further minimize measurement error. Refer to Fig.
D for optimum measuring thermocouple location.
Thermal Derating
Load current vs. ambient temperature and airflow
rates are given in Figs. x.1 to x.2 for maximum
temperature of 120 °C. Ambient temperature was
varied between 25 °C and 85 °C, with airflow rates
from 30 to 500 LFM (0.15m/s to 2.5 m/s), and
vertical and horizontal converter mounting. The
airflow during the testing is parallel to the long axis
of the converter, going from input pins to output
pins.
For each set of conditions, the maximum load
current was defined as the lowest of:
(i) The output current at which any MOSFET
temperature
specified temperature (120 °C) as indicated by the
thermographic image, or
(ii) The maximum current rating of the converter
(10A)
During normal operation, derating curves with
maximum FET temperature less than or equal to
120 °C should not be exceeded. Temperature on
the PCB at the thermocouple location shown in
Fig. D should not exceed 120 °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F ceramic
capacitor.
The output voltage ripple and input reflected ripple
current waveforms are obtained using the test
setup shown in Fig. E.
