Electrical Characteristics Notes
1. Converter will undergo input over-voltage shutdown.
2. Derate output power to 50% of rated power at Tcase = 135ºC. 135ºC is above specified operating range.
3. High or low state of input voltage must persist for about 200µs to be acted on by the shutdown circuitry.
4. Current limit inception is defined as the point where the output voltage has dropped to 90% of its nominal value. See Current Limit discussion in
Features Description section.
5. Parameter not tested but guaranteed to the limit specified.
6. Load current transition time ≥ 10µs.
7. Line voltage transition time ≥ 100µs.
8. Input voltage rise time ≤ 250µs.
9. Operating the converter at a synchronization frequency above the free running frequency will cause the converter’s efficiency to be slightly reduced
and it may also cause a slight reduction in the maximum output current/power available. For more information consult the factory.
10. After a disable or fault event, module is inhibited from restarting for 100ms. See Shut Down section of the Control Features description.
11. Only the ES and HB grade products are tested at three temperatures. The C grade products are tested at one temperature. Please refer to the
Construction and Environmental Stress Screening Options table for details.
12. These derating curves apply for the ES and HB grade products. The C grade product has a maximum case temperature of 70ºC.
13. The regulation stage operates to control the positive output. The negative output displays the cross regulation.
14. All +Vout and -Vout voltage measurements are made with Kelvin probes on the output leads.
15. The specified operating case tmeperature for ES products is -45ºC to 100 ºC. The specified operating case temperature for C grade products is
0ºC to 70ºC.

output over-voltage limit. There is also an output current
limit that is nearly constant as the load impedance decreases
(i.e., there is not fold-back or fold-forward characteristic to
the output current under this condition). When a load fault
is removed, the output voltage rises exponentially to its
nominal value without an overshoot. If a load fault pulls the
output voltage below about 60% of nominal, the converter
will shut down to attempt to clear the load fault. After a
short delay it will try to auto-restart.
BASIC OPERATION AND FEATURES
The MQBL DC/DC converter uses a two-stage power
conversion topology. The first, or regulation, stage is a
buck-converter that keeps the output voltage constant over
variations in line, load, and temperature. The second, or
isolation, stage uses transformers to provide the functions of
input/output isolation and voltage transformation to achieve
the output voltage required.
The MQBL converter’s control circuit does not implement an
over-temperature shutdown.
In the dual output converter there are two secondary
windings in the transformer of the isolation stage, one for
each output. There is only one regulation stage, however,
and it is used to control the positive output. The negative
output therefore displays “Cross-Regulation”, meaning that
its output voltage depends on how much current is drawn
from each output.
The following sections describe the use and operation of
additional control features provided by the MQBL converter.
CONTROL FEATURES
Both the positive and the negative outputs share a common
5V
OUTPUT RETURN pin.
82.5K
Both the regulation and the isolation stages switch at a fixed
frequency for predictable EMI performance. The isolation
stage switches at one half the frequency of the regulation
stage, but due to the push-pull nature of this stage it creates
a ripple at double its switching frequency. As a result, both
the input and the output of the converter have a fundamental
ripple frequency of about 550 kHz in the free-running mode.

Rectification of the isolation stage’s output is accomplished
with synchronous rectifiers. These devices, which are
MOSFETs with a very low resistance, dissipate far less energy
than would Schottky diodes. This is the primary reason why
the MQBL converters have such high efficiency, particularly at
low output voltages.
Figure A: Circuit diagram shown for reference only, actual circuit
components may differ from values shown for equivalent circuit.
ENABLE: The MQBL converter has one enable pin, ENA1
(pin 4), which is referenced with respect to the converter’s
input return (pin 2). It must have a logic high level for the
converter to be enabled; a logic low inhibits the converter.
Besides improving efficiency, the synchronous rectifiers
permit operation down to zero load current. There is no
longer a need for a minimum load, as is typical for converters
that use diodes for rectification. The synchronous rectifiers
actually permit a negative load current to flow back into the
converter’s output terminals if the load is a source of short
or long term energy. The MQBL converters employ a “back-
drive current limit” to keep this negative output terminal
current small.
The enable pin is internally pulled high so that an open
connection will enable the converter. Figure A shows the
equivalent circuit looking into the enable pin. It is TTL
compatible and has hysteresis.
SHUT DOWN: The MQBL converter will shut down in
response to only five conditions: ENA input low, VIN input
below under-voltage shutdown threshold, VIN input above
over-voltage shutdown threshold, output voltage below the
output under-voltage threshold, and output voltage above
the output over-voltage threshold. Following any shutdown
event, there is a startup inhibit delay which will prevent the
converter from restarting for approximately 100ms. After
the 100ms delay elapses, if the enable inputs are high and
the input voltage is within the operating range, the converter

resistor, Rtrim up, should be connected between TRIM pin
(pin 10) and the OUTPUT RETURN pin (pin 8), as shown in
Figure D. The value of this resistor should be determined
according to the following equation of from Figure E:
SYNCHRONIZATION: The MQBL converter’s switching
frequency can be synchronized to an external frequency
source that is in the 500 kHz to 700 kHz range. A pulse
train at the desired frequency should be applied to the SYNC
IN pin (pin 6) with respect to the INPUT RETURN (pin 2).
This pulse train should have a duty cycle in the 20% to 80%
range. Its low value should be below 0.8V to be guaranteed
to be interpreted as a logic low, and its high value should
be above 2.0V to be guaranteed to be interpreted as a logic
high. The transition time between the two states should be
less than 300ns.
Rtrim up(Ω) = 8300Ω*Vnom
- 41700Ω
Vout - Vnom
where:
Vnom = the converter’s nominal output voltage,
Vout = the desired output voltage (greater than
Vnom), and
Rtrim up is in Ohms.
As the output voltage is trimmed up, it produces a greater
voltage stress on the converter’s internal components
and may cause the converter to fail to deliver the
desired output voltage at the low end of the input
voltage range at the higher end of the load current and
temperature range. Please consult the factory for details.
To trim the output voltage below its nominal value, connect
an external resistor (Rtrim down) between the TRIM pin
and the POSITIVE OUTPUT pin (pin 7), and another resistor
(Rtrim sense) connected between the TRIM pin and the
OUTPUT RETURN pin as shown in Figure D. The values of
these trim down resistors should be chosen according to the
following equation or from Figure E:
If the MQBL converter is not to be synchronized, the SYNC
IN pin should be left open circuit. The converter will
then operate in its free-running mode at a frequency of
approximately 550 kHz.
If, due to a fault, the SYNC IN pin is held in either a logic low
or logic high state continuously, or the SYNC IN frequency
is outside the 500-700 kHz range, the MQBL converter will
revert to its free-running frequency.
The MQBL converter also has a SYNC OUT pin (pin 5). This
output can be used to drive the SYNC IN pins of as many as
ten (10) other MQBL converters. The pulse train coming out
of SYNC OUT has a duty cycle of 50% and a frequency that
matches the switching frequency of the converter with which
it is associated. This frequency is either the free-running
frequency if there is no valid synchronization signal at the
SYNC IN pin, or the synchronization frequency if there is.

INPUT UNDER-VOLTAGE SHUTDOWN: The MQBL
converter has an under-voltage shutdown feature that
ensures the converter will be off if the input voltage is too
low. The input voltage turn-on threshold is higher than
the turn-off threshold. In addition, the MQBL converter will
not respond to a state of the input voltage unless it has
remained in that state for more than about 200µs. This
hysteresis and the delay ensure proper operation when the
source impedance is high or in a noisy environment.

OUTPUT OVER-VOLTAGE SHUTDOWN: The MQBL
converter will shut down if the voltage at its power output
pins ever exceeds about 130% of the nominal value. The
shutdown threshold does not change with output trim or
sense drops; excessive trim-up or output wiring drops may
cause an output over-voltage shutdown event. After a
startup inhibit delay, the converter will attempt to restart.
Output Voltage Adjustment
Figure E: Trim up and Trim down as a function of external trim resistance.
BACK-DRIVE CURRENT LIMIT: Converters that use
MOSFETs as synchronous rectifiers are capable of drawing
a negative current from the load if the load is a source of
short- or long-term energy. This negative current is referred
to as a “back-drive current”.
OUTPUT UNDER-VOLTAGE SHUTDOWN: The MQBL
converter will also shut down if the voltage at its power
output pins ever dips below 60% of the nominal value for
more than a few milliseconds. Output voltage reduction
due to output current overload (current limit) is the most
common trigger for this shutdown. The shutdown threshold
does not change with output trim but at only 10%, trim-
down should not trigger this event. After a startup inhibit
delay, the converter will attempt to restart. This shutdown
is disabled during startup.
Conditions where back-drive current might occur include
paralleled converters that do not employ current sharing.
It can also occur when converters having different output
voltages are connected together through either explicit or
parasitic diodes that, while normally off, become conductive
during startup or shutdown. Finally, some loads, such as
motors, can return energy to their power rail. Even a load
capacitor is a source of back-drive energy for some period of
time during a shutdown transient.

as 5-10ºC different at full power and at high temperatures.
It is suggested that a thermocouple be attached directly to
the converter’s case through a small hole in the plate when
investigating how hot the converter is getting. Care must
also be made to ensure that there is not a large thermal
resistance between the thermocouple and the case due to
whatever adhesive might be used to hold the thermocouple
in place.
CURRENT LIMIT: In the event of excess load, the MQBL
converter will quickly reduce its output voltage to keep
the load current within safe limits (see Figure 12). If the
overload persists for more than 14 milliseconds, the converter
will shut off, wait a restart delay, and then automatically
attempt to re-start. The timeout is internally implemented
with an integrator: counting up whenever current limit is
active, and counting down at 1/5th the rate whenever current
limit becomes inactive. In this way a series of short-duration INPUT SYSTEM INSTABILITY: This condition can occur

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.
THERMAL CONSIDERATIONS: Figure 11 shows the
suggested Power Derating Curves for this converter as
a function of the case temperature and the maximum
desired power MOSFET junction temperature. All other
components within the converter are cooler than its hottest
MOSFET, which at full power is no more than 20ºC higher
than the case temperature directly below this MOSFET.
The Mil-HDBK-1547A component derating guideline calls for
a maximum component temperature of 105ºC. Figure 11
therefore has one power derating curve that ensures this limit
is maintained. It has been SynQor’s extensive experience that
reliable long-term converter operation can be achieved with
a maximum component temperature of 125ºC. In extreme
cases, a maximum temperature of 145ºC is permissible, but not
recommended for long-term operation where high reliability is
required. Derating curves for these higher temperature limits
are also included in Figure 11. The maximum case temperature
at which the converter should be operated is 135ºC.
