The RailQor® 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, even at low output power levels. Power dissipation
is so low that no heatsink is necessary to operate at full power at
85°C in an enclosed environment without airflow. Each module
is supplied completely encased to provide protection from the
harsh environments seen in many industrial and transportation
applications.

BASIC OPERATION AND FEATURES
CONTROL 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.
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(-).
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. Conductive
cooling design can be used with heat sink or cold plate cooling
systems. Full power is available with baseplate temperature up
to 110°C.
This series of converters use the industry standard footprint and
pin-out configuration.
ON/OFF
The ON/OFF signal is active low (meaning that a low voltage turns
the converter on). Figure A details four possible circuits for driving
the ON/OFF pin.
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.

Specification
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.
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 =
(
Δ% =
|
) - 10.22 [kΩ]
511
Δ%
where
Vnominal – Vdesired
Vnominal
| x 100%
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:
Rtrim-up =
(
5.11VOUT x (100+Δ%)
1.225Δ%
-
511
Δ%
- 10.22
)
[kΩ]
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 filtered 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.
RQ1BxxxQMXxx
Protection Features
Input Under-Voltage Lockout: The converter is designed
to turn off when the input voltage is too low, helping to avoid
an input system instability problem, which is described in more
detail in the application note titled “Input System Instability” on
www.synqor.com. 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* 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 CurrentLimit 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 “OverTemperature 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*.
Transient and Surge Protection: The wide input range of the
RailQor line of converters covers all transient requirements of EN
50155. For short duration transients and surges found in other
standards (such as RIA 12) that exceed the maximum input voltage
rating of the converter, SynQor has provided a design guide for a
transient suppression circuit. Please consult the application note
"Rail Power Applications" on our website www.synqor.com.

Input System Instability: This condition can occur because any
DC-DC converter appears incrementally as a negative resistance
load. A detailed application note titled “Input System Instability” is
available on the SynQor website which provides an understanding
of why this instability arises, and shows the preferred solution for
correcting it.

Application Section
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
six ways that the converter can be shut down, initiating a Startup Inhibit
Period:
•
•
•
•
•
•
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 110 ºC. As long as the user’s thermal system keeps TB
< 110 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, RTH-BA, 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 110 ºC.
Figure E shows three turn-on scenarios, where a Startup Inhibit Period is
initiated at t0, t1, and t2:
Pdiss
max
=
110 ºC - TA
RTH-BA
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.
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.
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.
For convenience, power derating curves for an encased converter without
a heatsink are provided for each output voltage.

Technical
Specification
Application Section
Designing for Maximizing Available Power: RailQor products
have been designed for full power operation in demanding thermal
environments. However, there are techniques that can be applied
external to the converter to ensure the best possible thermal
performance. These include correctly applying a heatsink to the
baseplate of the converter and maximizing the heat transferred
through the pins. The following discussions are only guidelines
and may not be necessary depending on the application
Optimal Heatsink Application: There are two key components
to maximizing the thermal dissipation when using a heatsink. One
is minimizing the thermal resistance between the converter and
the heatsink itself. There are imperfections between the mating
surfaces that reduce contact area between the two. A suitable
thermally conductive interface material should be used to maintain
a good thermal connection. A commonly used example is thermal
grease. When utilizing the threaded inserts on the baseplate of
a SynQor converter, care must be taken not to exceed the torque
or screw depth guidelines found in the mechanical diagram. Two,
airflow must be directed to pass between the fins of the heatsink
to maximize the surface area for heat removal.
Heatsinks are often available with both transverse and longitudinal
fin direction to allow system flexibility. Care should be taken to
avoid large external components surrounding the converter from
blocking airflow.

RQ1BxxxQMXxx
Layout Considerations: Significant performance improvement
can be made by designing a printed circuit board to properly sink
heat away from the converter through its pins. The first step is
to ensure a correctly formed solder joint at each pin. A smooth
fillet and complete barrel fill should be observed at the boundary
of pin and mounting hole to ensure maximum heat conduction
from pin to board (Figure F). It is worth noting here that encased
SynQor products are not compatible with reflow processes as it
may disrupt the placement of internal components.
The board itself should also have as many layers and as high of
copper weight as is practical for the application. Large ground
and power planes are best as the most heat will be conducted
through the large power pins of the converter on both input
and output sides. The heat must also have a path to conduct
from the copper planes of the board to the outside environment.
The typical FR4 material used in construction of a printed circuit
board is greater than 1000 times less thermally conductive than
copper and will act as an insulator between each copper plane.
To mitigate this, generous use of thermal vias is recommended
in the board area surrounding and below the converter. A proper
density of vias allows heat to conduct from the board to the air
while maintaining a large amount of copper area to conduct to
the vias. For reference, boards used in SynQor thermal testing
are 6 layer, 2 oz. copper boards with 50 mil diameter thermal
vias at a density of 36/in2 (Figure G).
