Operating information continued
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 immediately (latching). The
product can be restarted by cycling the input voltage or using
the remote control function.
Over Voltage Protection (OVP)
The products have latching output over voltage protection that
immediately will shut down the product in over voltage
conditions. The product can be restarted by cycling the input
voltage or using the remote control function.
Over Current Protection (OCP)
The products 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
I
the overload. The load distribution should be designed for the
maximum output short circuit current specified.

Checked
(MICMALE)
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.
