DC-DC Converter
The InQor® Sixteenth-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.

BASIC OPERATION AND FEATURES
CONTROL FEATURES
This converter switches 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.
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.
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
extreme situations.
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
This series of converters uses the industry standard footprint
and pin-out configuration.
[Vout(+) - Vout(-)] – [Vsense(+) - Vsense(-)] <
Sense Range % x Vout
ON/OFF
ON/OFF
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.

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
at http://www.synqor.com/support-technical-documents.html.
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

where

Output Current Limit: If the output current exceeds the
Output Current Limit threshold, the converter turns off. The
converter then enters a ‘hiccup mode’ where it repeatedly
turns on and off with a 350ms (typical) off time at small duty
cycle until the short circuit condition is removed. This prevents
excessive heating of the converter or the load board.
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
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.

Graphs on Page 3 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.
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
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.
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 bypassed to eliminate noise.

Figure F shows three turn-on scenarios, where a Startup Inhibit

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 , of the chosen heatsink

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.

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 100 ºC.

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.
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 100 ºC. As long as the user’s thermal
system keeps TB < 100 ºC, the converter can deliver its full
rated power.
