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 Tref as defined in thermal consideration section
exceeds 135°C the converter will shut down. The DC/DC
converter will make continuous attempts to start up (non-
latching mode) and resume normal operation automatically
when the temperature has dropped >10°C below the
temperature threshold.
The converters with latching option will shut down the module
when Tref exceeds 135°C and remain shut down until the
module restarts by switching on/off the input voltage or
Remote control.
Over Voltage Protection (OVP)
The converters have output over voltage protection that will
shut down the converter in over voltage conditions. The
converter will make continuous attempts to start up (non-
latching mode) and resume normal operation automatically
after removal of the over voltage condition.
The converters with latching option will shut down the module
in over voltage condition and remain shut down until the
converter restarts by switching on/off the input voltage or
Remote control.
Over Current Protection (OCP)
The converters include current limiting circuitry for protection
at continuous overload.
The output voltage will decrease towards 30% of nominal
output voltage for output currents in excess of max output
current (max IO). When reaching 30% of nominal output
voltage the converter will go into hic-up mode. 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.
The converters with latching option will shut down the module
when reaching 30% of nominal output voltage and remain
shut down until the converter restarts by switching on/off the
input voltage or Remote control.
Pre-bias Start-up
The converter has a Pre-bias start up functionality. The
converter will sink current in a controlled way during start up
if a pre-bias source is present at the output terminals.
