Thermal Consideration
General
The converters are designed to operate in different thermal
environments and sufficient cooling must be provided to
ensure reliable operation.
Cooling is achieved mainly by conduction, from the pins to the
host board, and convection, which is dependent on the airflow
across the converter. 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 DC/DC converter 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 reference point. The
temperature at this position should not exceed the max values
provided in the table below.
See Design Note 019 for further information.

Definition of reference temperature (Tref)
The reference temperature is used to monitor the temperature
limits of the product. Temperatures above maximum Tref are
not allowed and may cause degradation or permanent
damage to the product. Tref is also used to define the
temperature range for normal operating conditions.
Tref is defined by the design and used to guarantee safety
margins, proper operation and high reliability of the module.
