REINFORCED
Insulation
The InQor quarter-brick converter series is composed
of next-generation, board-mountable, isolated
(REINFORCED), 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.

Application Section
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.
5V
50k
50k
ON/OFF
Vin(-)
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.
TTL
100pF
Figure B: Internal ON/OFF pin circuitry
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
demanding applications.
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 load 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
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.
Sense Range % = Trim-up Range % (usually 10 %)
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.

Application Section
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.
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.
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

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
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 overload is removed. This prevents excessive
heating of the converter or the system 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 overload 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.

Trim graphs show the relationship between the trim resistor
value 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.
Over-Temperature Shutdown: A temperature sensor on
the internal converter PCB 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.
Do not add decoupling 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 sensing voltage
drops, should not be greater than that specified for the output
voltage trim range.

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:
Thermal Considerations: The maximum operating baseplate
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.
•ꢀ InputꢀUnder-VoltageꢀLockout
A power derating curve can be calculated for any heatsink that is
attached to the baseplate of the converter. It is only necessary to
determine the thermal resistance, RTHBA, of the chosen heatsink
between the baseplate and the ambient air for a given airflow
rate. This information is available from the heatsink vendor. The
following formula can then be used to determine the maximum
power the converter can dissipate for a given thermal condition if
its baseplate is to be no higher than 100 ºC.

Before time t0, when the input voltage is below the UVL threshold,
the unit is disabled by the Input Under-Voltage Lockout (UVL)
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.
This value of power dissipation can then be used in conjunction
with the data shown in Figure 2 to determine the maximum load
current (and power) that the converter can deliver in the given
thermal condition.
We recommend that a suitable thermal interface material such as
a thermally conductive pad or grease be used to assure a good
thermal interface between the base plate and the conductive
cooling device.
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.
