Operating information continued
Parallel Operation
Two converters may be paralleled for redundancy if the total
power is equal or less than PO max. It is not recommended to
parallel the converters without using external current sharing
circuits.
See Design Note 006 for detailed information.
Remote Sense
The DC/DC converters have remote sense that can be used to
compensate for voltage drops between the output and the
point of load. The sense traces should be located close to the
PCB ground layer to reduce noise susceptibility. The remote
sense circuitry will compensate for up to 10% voltage drop
between output pins and the point of load.
If the remote sense is not needed +Sense should be
connected to +Out and -Sense should be connected to -Out.
Over Temperature Protection (OTP)
The converters are protected from thermal overload by an
internal over temperature shutdown circuit.
When the baseplate temperature (center of baseplate)
exceeds 140°C the converter will shut down(latching). The
DC/DC converter can be restarted by cycling the input voltage
or using the remote control function.
Over Voltage Protection (OVP)
The converters have latching output overvoltage protection. In
the event of an overvoltage condition, the converter will
shutdown immediately. The converter can be restarted by
cycling the input voltage or using the remote control function.
Over Current Protection (OCP)
The converters include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards zero for output
currents in excess of max output current (max Io). The
converter will resume normal operation after removal of the
overload. The load distribution should be designed for the
maximum output short circuit current specified.
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 product. 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
VI = 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 608 x 203 mm.
For products with base plate used in a sealed box/cold wall
application, cooling is achieved mainly by conduction
throughthe cold wall. The Output Current Derating graphs are
found in the Output section for each model. The product is
tested in a sealed box test set up with ambient temperatures
85, 55 and 35°C. See Design Note 028 for further details.
