BASIC OPERATION AND FEATURES
CONTROL FEATURES
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.
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.
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 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.
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.
This series of converters uses the industry standard footprint
and pin-out configuration.

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.
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 =
(
90.9
Δ%
) - 0.909 (kΩ)
where
Δ% =
|
Vnominal – Vdesired
Vnominal
| x 100%
To increase the output voltage, the user should connect a
resistor between Pin 6 (TRIM) and Pin 7 (SENSE(+) input).
For a desired increase of the nominal output voltage, the
value of the resistor should be:
Rtrim-up =
(
1.0VOUT x (100+Δ%)
1.225Δ%
-
90.9
Δ%
- 0.909
) (kΩ)
where
Vout = Nominal Output Voltage
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 overvoltage 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.
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.

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”
available 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 (listed on the specification 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. Also see Figure D.
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 Current-Limit Shutdown Voltage, the converter turns off.
The converter then enters a “hiccup” mode where it
repeatedly turns on and off at a 2.23 Hz (nominal) frequency
with 11% 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 400 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 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.

Startup Inhibit Period: The Startup Inhibit Period
ensures that the converter will remain off for approximately
400 ms when it is shut down for any reason. When an
output short is present, this generates a 2.23 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:
When the ON/OFF pin goes high after t2, the

Period
has
elapsed,
and
the
output turns on within the typical Turn-On Time.
Thermal Considerations: The maximum operating
base-plate temperature, TB, is 90 ºC. Refer to the
thermal derating curve, Figure 5, to see the available
output current at baseplate temperatures below 90 ºC.

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, RTHBA, 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 then be used to determine the maximum power the
converter can dissipate for a given thermal condition:
Input Under-Voltage Lockout
Input Over-Voltage Lockout
Output Over-Voltage Protection
Over Temperature Shutdown
Current Limit
Short Circuit Protection
Turned off by the ON/OFF input
Figure E shows three turn-on scenarios, where a Startup
Inhibit Period is initiated at t0, t1, and t2:
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.

RTHBA
This value of power dissipation can then be used in
conjunction with the data shown in Figure 3 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.

Application Section
Full-Featured Application Notes
This section provides some basic application information for
the full-feature version of the MCOTS series converter.
All units in this product family include back-drive protection
to simplify the use of multiple converters in a parallel or
sequencing application. However, any voltage applied to
the output of the converter should be kept below 110% of
the rated output voltage of the converter.
In addition to back-drive protection, these units include the
following features (pins):
Current Share (pin C): The active current share feature
allows for N+1(less than 30) parallel applications. To
achieve load sharing, directly connect the I share pins of
multiple units. The load current will share equally among the
multiple units (±5% at full rated current). It is important
that the Vin(-) pins of the sharing units be directly connected
and NOT placed outside of an EMI filter or other impedance
path. The voltage at the I Share pin will range from 0.4 to
4 volts (at full rated current), referenced to the primary-side
ground, Vin(-).
Clock Sync (pin A): The External Clock Synchronization pin
provides the ability for the user to control the EMI signature
and synchronize sensitive circuitry to quiet periods in the
converter operation. With this option, the converter can be
synchronized to an external clock signal whose frequency
is greater than that of the free-running internal clock.
However, substantially raising the converter’s frequency
will reduce its efficiency. Therefore, the recommended
frequency range for the external clock synchronization
signal is being specified in electrical characterization table,
with 50% duty cycle.
The following requirements should also be met:
• The external clock signal should be referenced to the
negative input voltage, Vin(-)
• The high level of the signal should be between
3.5V and 5.0V.
• The low level should be between -0.5V and +1.2V.
• Do not apply a clock sync or change frequency while
unit is runnig.
• For using more than 5 units in parallel Contact SynQor.
Start Sync (pin B): The Start Synchronization pin will
allow a more consistent start-up sequence. To operate this
feature, connect together the Start-Sync pins of multiple
current-sharing units. This will permit immediate start-up
with loads greater than the current limit of a single unit.
Without this connection, any set of converters attempting to
asynchronously start (or re-start) with a load greater than
the current limit of a single unit will “hiccup”. This “hiccup”
mode will continue until one converter attempts a start at
the same time as the minimum number of additional units
necessary to sustain the load condition. For example, three
50 amp units starting into a 90 amp load would require
two units to simultaneously attempt a start. The Start
Sync connection synchronizes these starting attempts and
provides a more consistent and reliable start-up sequqnce.
For details about the “hiccup” mode or repeated startup
attempts, please see the “Startup Inhibit Period” note in the
Technical Specification.
