BASICOPERATIONANDFEATURES
This converter series uses a two-stage power conversion
topology. The first stage is a buck-converter that keeps the
output voltage constant over variations in line, load, and
temperature. The second stage uses a transformer to provide
the functions of input/output isolation and voltage step-up or
step-down to achieve the output voltage required.
Both the first stage and the second stage switch at a fixed
frequency for predictable EMI performance. Rectification of
the transformer’s output is accomplished with synchronous
rectifiers. These devices, which are MOSFETs with a very low
on-state resistance, dissipate far less energy than Schottky
diodes. This is the primary reason that the converter has such
high efficiency, even at very low output voltages and very high
output currents.
These converters are offered totally encased to withstand harsh
environmentsandthermallydemandingapplications.Dissipation
throughout the converter is so low that it does not require a
heatsink for operation in many applications; however, adding
a heatsink provides improved thermal derating performance in
extreme si tuations.
This series of converters use the industry standard footprint and
pin-out configuration.
CONTROLFEATURES
REMOTE ON/OFF (Pin 2):TheON/OFFinput,Pin2,permits
the user to control when the converter is on or off. This input
is referenced to the return terminal of the input bus, Vin(-).
TheON/OFFsignalisactivelow(meaningthatalowturnsthe
converteron).FigureAdetailsfourpossiblecircuitsfordriving
theON/OFFpin.FigureBisadetailedlookoftheinternalON/
OFFcircuitry.
REMOTE SENSE(+) (Pins 7 and 5): The SENSE(+) inputs
correct for voltage drops along the conductors that connect the
converter’soutputpinstotheload.
Pin 7 should be connected to Vout(+) and Pin 5 should be
connectedtoVout(-)atthepointontheboardwhereregulation
is desired. A remote connection at the load can adjust for a
voltage drop only as large as that specified in this datasheet,
that is
[Vout(+)-Vout(-)]–[Vsense(+)-Vsense(-)] <
SenseRange%xVout
Pins 7 and 5 must be connected for proper regulation of
the output voltage. If these connections are not made, the
converter will deliver an output voltage that is slightly higher
than its specified value.
Note: the output over-voltage protection circuit senses the
voltage across the output (pins 8 and 4) to determine when
it should trigger, not the voltage across the converter’s sense
leads(pins7and5).Therefore,theresistivedropontheboard
should be small enough so that output OVP does not trigger,
even during load transients.

OUTPUT VOLTAGE TRIM (Pin 6):TheTRIMinputpermitsthe
usertoadjusttheoutputvoltageacrossthesenseleadsupor
down according to the trim range specifications.
To decrease the output voltage, the user should connect a
resistorbetweenPin6andPin5(SENSE(-)input).Foradesired
decrease of the nominal output voltage, the value of the resistor
should be
Rtrim-down =
(
511
)

where
∆% =
Vnominal–Vdesired
x100%
Vnominal
To increase the output voltage, the user should connect a
resistorbetweenPin6andPin7(SENSE(+)input).Foradesired
increase of the nominal output voltage, the value of the resistor
should be
Trim graphs show the relationship between the trim resistor
valueandRtrim-upandRtrim-down,showingthetotalrangethe
output voltage can be trimmed up or down.
Note:theTRIMfeaturedoesnotaffectthevoltageatwhichthe
output over-voltage protection circuit is triggered. Trimming the
output voltage too high may cause the over-voltage protection
circuit to engage, particularly during transients.
It is not necessary for the user to add capacitance at the Trim
pin. The node is internally bypassed to eliminate noise.
Total DC Variation of VOUT:Fortheconverter to meet itsfull
specifications, the maximum variation of the dc value of VOUT,
due to both trimming and remote load voltage drops, should not
be greater than that specified for the output voltage trim range.
PROTECTIONFEATURES
Input Under-Voltage Lockout: The converter is designed
to turn off when the input voltage is too low, helping avoid an
input system instability problem, described in more detail in
the application note titled “
Input System Instability
” on our
website. The lockout circuitry is a comparator with dc hysteresis.
When the input voltage is rising, it must exceed the typical Turn-
On Voltage Threshold value (listed on the specifications page)
before the converter will turn on. Once the converter is on,
the input voltage must fall below the typical Turn-Off Voltage
Threshold value before the converter will turn off.
Output Current Limit: The maximum current limit remains
constant as the output voltage drops. However, once the
impedance of the load across the output is small enough to make
theoutputvoltagedropbelowthespecifiedOutputDCCurrent-
LimitShutdownVoltage,theconverterturnsoff.
Theconverterthenentersa“hiccupmode”whereitrepeatedly
turnsonandoffata5Hz(nominal)frequencywitha5%duty
cycle until the short circuit condition is removed. This prevents
excessive heating of the converter or the load board.
Output Over-Voltage Limit:Ifthevoltageacrosstheoutput
pinsexceedstheOutputOver-VoltageProtectionthreshold,the
converter will immediately stop switching. This prevents damage
totheloadcircuitdueto1)excessiveseriesresistanceinoutput
current path from converter output pins to sense point, 2) a
releaseofashort-circuitcondition,or3)areleaseofacurrent
limit condition. Load capacitance determines exactly how high
theoutputvoltagewillriseinresponsetotheseconditions.After
200mstheconverterwillautomaticallyrestart.
Over-Temperature Shutdown: A temperature sensor on
the converter senses the average temperature of the module.
The thermal shutdown circuit is designed to turn the converter
off when the temperature at the sensed location reaches the
Over-Temperature Shutdown value. It will allow the converter
to turn on again when the temperature of the sensed location
fallsbytheamountoftheOver-TemperatureShutdownRestart
Hysteresis value.

Input Filtering and External Capacitance:
FigureD
provides
a diagram showing the internal input filter components. This filter
dramatically reduces input terminal ripple current, which otherwise
could exceed the rating of an external electrolytic input capacitor.

Startup Inhibit Period:TheStartupInhibitPeriodensuresthat
theconverterwillremainoffforapproximately200mswhenitis
shut down for any reason. When an output short is present, this
generates a 5 Hz “hiccup mode,” which prevents the converter
from overheating. In all, there are seven ways that the converter
canbeshutdown,initiatingaStartupInhibitPeriod:
• InputUnder-VoltageLockout
• InputOver-VoltageShutdown
• OutputOver-VoltageProtection
• OverTemperatureShutdown
• CurrentLimit
• ShortCircuitProtection
• TurnedoffbytheON/OFFinput
FigureEshowsthreeturn-onscenarios,whereaStartupInhibit
Period is initiated at t0, t1, and t2:
Beforetimet0,whentheinputvoltageisbelowtheUVLthreshold,
theunitisdisabledbytheInputUnder-VoltageLockoutfeature.
WhentheinputvoltagerisesabovetheUVLthreshold,theInput
Under-VoltageLockoutisreleased,andaStartupInhibitPeriodis
initiated.Attheendofthisdelay,theON/OFFpinisevaluated,
and since it is active, the unit turns on.
Attimet1,theunitisdisabledbytheON/OFFpin,anditcannot
beenabledagainuntiltheStartupInhibitPeriodhaselapsed.
When the ON/OFF pin goes high after t2, the Startup Inhibit
Period has elapsed, and the output turns on within the typical
Turn-OnTime.
Thermal Considerations: The maximum operating base-plate
temperature, TB,is100ºC.Aslongastheuser’sthermalsystem
keeps TB <100ºC,theconvertercandeliveritsfullratedpower.
Apowerderatingcurvecanbecalculatedforanyheatsinkthatis
attached to the base-plate of the converter. It is only necessary
todeterminethethermalresistance,RTHBA, of the chosen heatsink
between the base-plate and the ambient air for a given airflow
rate. This information is usually available from the heatsink
vendor. The following formula can the be used to determine the
maximum power the converter can dissipate for a given thermal
conditionifitsbase-plateistobenohigherthan100ºC.
