Parallel Operation
Two products may be paralleled for redundancy if the total
power is equal or less than P
parallel the products without using external current sharing
circuits.
See Design Note 006 for detailed information.
Remote Sense
The products 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 products are protected from thermal overload by an
internal over temperature shutdown circuit.
When T
135°C the product will shut down. The product will make
continuous attempts to start up (non-latching mode) and
resume normal operation automatically when the temperature
has dropped >15°C below the temperature threshold.
Over Voltage Protection (OVP)
The products have output over voltage protection that will shut
down the product in over voltage conditions. The product will
make continuous attempts to start up (non-latching mode) and
resume normal operation automatically after removal of the
over voltage condition.
Over Current Protection (OCP)
The products include current limiting circuitry for protection at
continuous overload.
PKMD standard module, the output voltage will decrease
towards zero for output currents in excess of max output
current (Iomax).
The converter will resume normal operation after removal of

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
V
The product is tested on a 254 x 254 mm, 35 µm (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 through
the cold wall. The Output Current Derating graphs are found in
the Output section for each module. The product is tested in a
sealed box test set up with ambient temperatures 85 and 35°C.

the overload. The load distribution system should be designed
to carry the maximum output short circuit current specified.
The PKMD series include hiccup OCP option, the output
voltage will decrease when the output current in excess of its
current limit point, when the load continue to increase to some
higher level, the module will enter into hiccup mode.
During hiccup, the module will try to restart and shutdown
again for the overload. When the overload is removed, the
products will continue to work normally.
