A
Thermal Consideration
General
The products are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
For products mounted on a PCB without a heat sink attached
cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependant on the
airflow across the product. Increased airflow enhances the
cooling of the converter.
The Output Current Derating graph found in the Output
section for each model provides the available output current
vs. ambient air temperature and air velocity at Vin = 53 V.
The product is tested on a 254 x 254 mm,
35 m (1 oz), 16-layer test board mounted vertically in a wind
tunnel with a cross-section of 305 x 305 mm.
Proper cooling of the DC/DC converter can be verified by
measuring the temperature at positions P1, P2, P3, P4 and
P5. The temperature at these positions should not exceed the
max values provided in the table below. The number of points
may vary with different thermal design and topology.
See Design Note 019 for detailed information.
