Adjustable Output 10-Amp SIP-mount DC/DC Converters
CAUTION : If you routinely or accidentally exceed these Derating guidelines,
the converter may have an unplanned Over Temperature shut down. Also, these
graphs are all collected at slightly above Sea Level altitude. Be sure to reduce
+VOUT
the derating for higher density altitude.

Output Current Limiting
Current limiting inception is de?ned as the point at which full power falls below
the rated tolerance. See the Performance/Functional Speci?cations. Note par-
-VOUT
C1 = 1μF
ticularly that the output current may brie?y rise above its rated value in normal
operation as long as the average output power is not exceeded. This enhances
reliability and continued operation of your application. If the output current is
too high, the converter will enter the short circuit condition.

Minimum Output Loading Requirements
All models regulate within speci?cation and are stable under no load to full
load conditions. Operation under no load might however slightly increase
output ripple and noise.
Thermal Shutdown
To prevent many over temperature problems and damage, these converters
include thermal shutdown circuitry. If environmental conditions cause the
temperature of the DC/DC’s to rise above the Operating Temperature Range
up to the shutdown temperature, an on-board electronic temperature sensor
will power down the unit. When the temperature decreases below the turn-on
threshold, the converter will automatically restart. There is a small amount of
hysteresis to prevent rapid on/off cycling. The temperature sensor is typically
located adjacent to the switching controller, approximately in the center of the
unit. See the Performance and Functional Speci?cations.
CAUTION: If you operate too close to the thermal limits, the converter may
shut down suddenly without warning. Be sure to thoroughly test your applica-
tion to avoid unplanned thermal shutdown.
Temperature Derating Curves
The graphs in this data sheet illustrate typical operation under a variety of
conditions. The Derating curves show the maximum continuous ambient air
temperature and decreasing maximum output current which is acceptable
under increasing forced air?ow measured in Linear Feet per Minute (“LFM”).
Note that these are AVERAGE measurements. The converter will accept brief
increases in current or reduced air?ow as long as the average is not exceeded.
Note that the temperatures are of the ambient air?ow, not the converter
itself which is obviously running at higher temperature than the outside air.
Also note that very low ?ow rates (below about 25 LFM) are similar to “natural
convection”, that is, not using fan-forced air?ow.
Murata Power Solutions makes Characterization measurements in a closed
cycle wind tunnel with calibrated air?ow. We use both thermocouples and an
infrared camera system to observe thermal performance.

Output Short Circuit Condition
When a converter is in current-limit mode, the output voltage will drop as the
output current demand increases. If the output voltage drops too low (approxi-
mately 98% of nominal output voltage for most models), the magnetically
coupled voltage used to develop primary side voltages will also drop, thereby
shutting down the PWM controller. Following a time-out period, the PWM will
restart, causing the output voltage to begin ramping up to its appropriate value.
If the short-circuit condition persists, another shutdown cycle will initiate. This
rapid on/off cycling is called “hiccup mode”. The hiccup cycling reduces the
average output current, thereby preventing excessive internal temperatures
and/or component damage. A short circuit can be tolerated inde?nitely.
The “hiccup” system differs from older latching short circuit systems
because you do not have to power down the converter to make it restart. The
system will automatically restore operation as soon as the short circuit condi-
tion is removed.
Remote On/Off Control
Please refer to the Connection Diagram on page 1 for On/Off connections.
Positive polarity models are enabled when the On/Off pin is left open or is
pulled high to +Vin with respect to –Vin. Positive-polarity devices are disabled
when the On/Off is grounded or brought to within a low voltage (see Speci?ca-
tions) with respect to –Vin.
Dynamic control of the On/Off function should be able to sink appropriate
signal current when brought low and withstand appropriate voltage when
brought high. Be aware too that there is a ?nite time in milliseconds (see
Speci?cations) between the time of On/Off Control activation and stable,
regulated output. This time will vary slightly with output load type and current
and input conditions.
Output Capacitive Load
These converters do not require external capacitance added to achieve rated
speci?cations. Users should only consider adding capacitance to reduce
switching noise and/or to handle spike current load steps. Install only enough
capacitance to achieve noise objectives. Excess external capacitance may
cause regulation problems, degraded transient response and possible oscilla-
tion or instability.
