Half-brick
DC-DC Converter
Isolation
®
The InQor Half-brick converter series is composed
of next-generation, board-mountable, isolated,
fixed switching frequency dc-dc converters that use
synchronous rectification to achieve extremely high
power conversion efficiency. Each module is supplied
completely encased to provide protection from the
harsh environments seen in many industrial and
transportation applications.

BASICꢀOPERATIONꢀANDꢀFEATURES
CONTROLꢀFEATURES
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
theꢀ functionsꢀ ofꢀ input/outputꢀ isolationꢀ andꢀ voltageꢀ step-upꢀ orꢀ
step-down to achieve the output voltage required.
RꢂMOꢁꢂ Oꢀ/OFF (Pin 2):ꢀTheꢀON/OFFꢀinput,ꢀPinꢀ2,ꢀpermitsꢀ
the user to control when the converter is on or off. This input
isꢀ referencedꢀ toꢀ theꢀ returnꢀ terminalꢀ ofꢀ theꢀ inputꢀ bus,ꢀ Vin(-).ꢀ
TheꢀON/OFFꢀsignalꢀisꢀactiveꢀlowꢀ(meaningꢀthatꢀaꢀlowꢀturnsꢀtheꢀ
converterꢀon).ꢀFigureꢀAꢀdetailsꢀfourꢀpossibleꢀcircuitsꢀforꢀdrivingꢀ
theꢀON/OFFꢀpin.ꢀFigureꢀBꢀisꢀaꢀdetailedꢀlookꢀofꢀtheꢀinternalꢀON/
OFFꢀcircuitry.
Both the first stage and the second stage switch at a fixed
frequencyꢀ forꢀ predictableꢀ EMIꢀ performance.ꢀ Rectificationꢀ ofꢀ
the transformer’s output is accomplished with synchronous
rectifiers.ꢀ Theseꢀ devices,ꢀ whichꢀ areꢀ MOSFETsꢀ withꢀ aꢀ veryꢀ lowꢀ
on-stateꢀ resistance,ꢀ dissipateꢀ farꢀ lessꢀ energyꢀ thanꢀ Schottkyꢀ
diodes. This is the primary reason that the converter has such
high efficiency, even at very low output voltages and very high
output currents.
RꢂMOꢁꢂ ꢃꢂꢀꢃꢂ(+) (Pins 7 and 5):ꢀ Theꢀ SENSE(+)ꢀ inputsꢀ
correct for voltage drops along the conductors that connect the
converter’s output pins to the load.
Pinꢀ 7ꢀ shouldꢀ beꢀ connectedꢀ toꢀ Vout(+)ꢀ andꢀ Pinꢀ 5ꢀ shouldꢀ beꢀ
connectedꢀtoꢀVout(-)ꢀatꢀtheꢀpointꢀonꢀtheꢀboardꢀwhereꢀregulationꢀ
isꢀ desired.ꢀ Aꢀ remoteꢀ connectionꢀ atꢀ theꢀ loadꢀ canꢀ adjustꢀ forꢀ aꢀ
voltage drop only as large as that specified in this datasheet,
that is
These converters are offered totally encased to withstand harsh
environmentsꢀandꢀthermallyꢀdemandingꢀapplications.ꢀDissipationꢀ
throughout the converter is so low that it does not require a
heatsinkꢀ forꢀ operationꢀ inꢀ manyꢀ applications;ꢀ however,ꢀ addingꢀ
a heatsink provides improved thermal derating performance in
extreme situations.

SenseꢀRangeꢀ%ꢀxꢀVout
Pinsꢀ 7ꢀ andꢀ 5ꢀ mustꢀ beꢀ connectedꢀ forꢀ properꢀ regulationꢀ ofꢀ
the output voltage. If these connections are not made, the
converter will deliver an output voltage that is slightly higher
than its specified value.
This series of converters use the industry standard footprint and
pin-out configuration.
Note:ꢀ theꢀ outputꢀ over-voltageꢀ protectionꢀ circuitꢀ sensesꢀ theꢀ
voltageꢀ acrossꢀ theꢀ outputꢀ (pinsꢀ 8ꢀ andꢀ 4)ꢀ toꢀ determineꢀ whenꢀ
it should trigger, not the voltage across the converter’s sense
leadsꢀ(pinsꢀ7ꢀandꢀ5).ꢀꢀTherefore,ꢀtheꢀresistiveꢀdropꢀonꢀtheꢀboardꢀ
shouldꢀ beꢀ smallꢀ enoughꢀ soꢀ thatꢀ outputꢀ OVPꢀ doesꢀ notꢀ trigger,ꢀ

PROTECTIONꢀFEATURES
Input Under-Voltage Lockout:ꢀ Theꢀ converterꢀ isꢀ designedꢀ
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 “Inputꢀ Systemꢀ Instability”ꢀ onꢀ ourꢀ
website. The lockout circuitry is a comparator with dc hysteresis.
When the input voltage is rising, it must exceed the typical Turn-
OnꢀVoltageꢀThresholdꢀvalueꢀ(listedꢀonꢀtheꢀspecificationsꢀpage)ꢀ
beforeꢀ theꢀ converterꢀ willꢀ turnꢀ on.ꢀ Onceꢀ theꢀ converterꢀ isꢀ on,ꢀ
theꢀ inputꢀ voltageꢀ mustꢀ fallꢀ belowꢀ theꢀ typicalꢀ Turn-Offꢀ Voltageꢀ
Threshold value before the converter will turn off.
To decrease the output voltage, the user should connect a
resistorꢀbetweenꢀPinꢀ6ꢀandꢀPinꢀ5ꢀ(SENSE(-)ꢀinput).ꢀForꢀaꢀdesiredꢀ
