Application Section
BASIC OPERATION AND FEATURES
The MQSA DC/DC converter uses a single stage power
conversion topology. A flyback-converter is used to keep
the output voltage constant over variations in line, load, and
temperature. The converter switches at a fixed frequency
for predictable EMI performance. Rectification of the output
is accomplished with diodes.
An input under-voltage shutdown feature with hysteresis is
provided, as well as an output over-voltage limit. There is
also an output current limit that is nearly constant as the
load impedance decreases. When a load fault is removed,
the output voltage rises exponentially to its nominal value
with minimal overshoot.
The following sections describe the use and operation of
additional control features provided by the MQSA converter.
CONTROL FEATURES
ENABLE: The MQSA converter has one enable pin, ENA
(pin 5), which is referenced with respect to the converter’s
input return (pin 7). It must have a logic high level for the
converter to be enabled; a logic low inhibits the converter.
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 MQSA converter will shut down in
response to only three conditions: ENA input low, VIN input
below under-voltage shutdown threshold, and output voltage
above the output over-voltage threshold.
INPUT UNDER-VOLTAGE SHUTDOWN: The MQSA
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.

CIRCUITRY
4.99K
18 .7K
OUTPUT OVER-VOLTAGE SHUTDOWN: The MQSA
converter will shut down if the voltage at its power output
pins ever exceeds about 130% of the nominal value.
CURRENT LIMIT: In the event of excess load, the MQSA
converter will quickly reduce its output voltage to keep the
load current within safe limits.
If the converter is connected to an external heatsink,
the heatsink will help to make the converter’s case top a
uniform temperature. How well it does so depends on the
thickness of the heatsink and on the thermal conductance of
the interface layer (e.g. thermal grease, thermal pad, etc.)
between the case and the heatsink. Unless this is done very
well, it is important not to mistake the heatsink’s temperature
for the maximum case temperature. It is easy for them to
be as much 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 heatsink 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.
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.
THERMAL CONSIDERATIONS: Figure 5 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
5 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 5. The
maximum case temperature at which the converter should
be operated is 135ºC.

MilQor® Hi-Rel converters and filters are offered in three variations of environmental stress screening options. All ES-Grade and HB-Grade MilQor
Hi-Rel converters use SynQor’s proprietary QorSeal® Hi-Rel assembly process that includes a Parylene-C coating of the circuit, a high performance
thermal compound filler, and a nickel barrier gold plated aluminum case. Each successively higher grade has more stringent mechanical and
electrical testing, as well as a longer burn-in cycle. The ES- and HB-Grades are also constructed of components that have been procured through an
element evaluation process that pre-qualifies each new batch of devices.
