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
Thermographic
capability is not available, then thermocouples may
be used. . It is recommended the use of AWG #40
gauge thermocouples to ensure measurement
accuracy. Careful routing of the thermocouple leads
will further minimize measurement error. Refer to

locations.

Thermal Derating
Load current vs. ambient temperature and airflow
rates are given in Figs. x.1 for maximum temperature
of 120 °C. Ambient temperature was varied between
25 °C and 85 °C, with airflow rates from 30 to 500
LFM (0.15 m/s to 2.5 m/s), and vertical converter
mounting. The airflow during the testing is parallel to
the short 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 does not exceed a maximum specified
temperature (120 °C) as indicated by the thermo-
graphic image, or
(ii) The maximum current rating of the converter
(16 A)
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.2 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.3 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.
