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.
RꢁMOTꢁ 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(-).ꢀ

Bothꢀ theꢀ firstꢀ stageꢀ andꢀ theꢀ secondꢀ stageꢀ switchꢀ atꢀ aꢀ fixedꢀ
frequencyꢀ forꢀ predictableꢀ EMIꢀ performance.ꢀ Rectificationꢀ ofꢀ
theꢀ transformer’sꢀ outputꢀ isꢀ accomplishedꢀ withꢀ synchronousꢀ
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.
RꢁMOTꢁ SꢁꢀSꢁ(+) (Pins 7 and 5):ꢀ Theꢀ SENSE(+)ꢀ inputsꢀ
correct for voltage drops along the conductors that connect the
converter’sꢀoutputꢀpinsꢀtoꢀtheꢀload.

isꢀ desired.ꢀ Aꢀ remoteꢀ connectionꢀ atꢀ theꢀ loadꢀ canꢀ adjustꢀ forꢀ aꢀ

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.

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.
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
itꢀ shouldꢀ trigger,ꢀ notꢀ theꢀ voltageꢀ acrossꢀ theꢀ converter’sꢀ senseꢀ

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.
