®
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.

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

step-down to achieve the output voltage required.
REMOTE ON/OFF (Pin 2):ꢀTheꢀON/OFFꢀinput,ꢀPinꢀ2,ꢀpermitsꢀ

high efficiency, even at very low output voltages and very high
output currents.

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.

userꢀtoꢀadjustꢀtheꢀoutputꢀvoltageꢀacrossꢀtheꢀsenseꢀleadsꢀupꢀorꢀ

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
