BASIC OPERATION AND FEATURES
CONTROL FEATURES
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(-).
This converter series uses
a
two-stage power conversion
topology. The first stage 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-down to achieve the low output voltage required.
In negative logic versions, the ON/OFF signal is active low
(meaning that a low voltage turns the converter on). In positive
logic versions, the ON/OFF input is active high (meaning that a
high voltage turns the converter on). Figure A details possible
circuits for driving the ON/OFF pin. Figure B is a detailed look of
the internal ON/OFF circuitry. See Ordering Information page for
available enable logics.
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 significantly less energy than Schottky
diodes, enabling the converter to achieve high efficiency.
REMOTE SENSE Pins 8(+) and 6(-): The SENSE(+) and
SENSE(-) inputs correct for voltage drops along the conductors
that connect the converter’s output pins to the load.
Pin 8 should be connected to Vout(+) and Pin 6 should be
connected to Vout(-) at the point on the board where regulation
is desired. If these connections are not made, the converter will
deliver an output voltage that is slightly higher than its specified
value.
Dissipation throughout the converter is so low that it does not
require a heatsink or even a baseplate for operation in many
applications; however, adding a heatsink provides improved
thermal derating performance in extreme situations. To further
withstand harsh environments and thermally demanding
applications, certain models are available totally encased. See
Ordering Information page for available thermal design options.
Note: The Output Over-Voltage Protection circuit senses the
voltage across the output (Pins 9 and 5) to determine when it
should trigger, not the voltage across the converter’s sense leads
(Pins 8 and 6). Therefore, the resistive drop on the board should
be small enough so that output OVP does not trigger, even during
load transients.
SynQor half-brick converters use the industry standard footprint
and pin-out.

user to adjust the output voltage across the sense leads up or down
according to the trim range specifications. SynQor uses industry
standard trim equations.

Application Section
The Trim Graph in Technical Features shows 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.
Protection Features
Input Under-Voltage Lockout (UVLO): 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 the SynQor website. 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.
It is not necessary for the user to add capacitance at the TRIM pin.
The node is internally filtered to eliminate noise.
Output Current Limit (OCP): If the output current exceeds
the “Output DC Current Limit Inception” value*, then a fast linear
current limit controller will reduce the output voltage to maintain
a constant output current. If as a result, the output voltage falls
below the “Output DC Current Limit Shutdown Voltage”* for more
than 50 ms, then the unit will enter into hiccup mode, with a 500
ms off-time. The unit will then automatically attempt to restart.
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.
Back-Drive Current Limit: If there is negative output current
of a magnitude larger than the “Back-Drive Current Limit while
Enabled” specification*, then a fast back-drive limit controller will
increase the output voltage to maintain a constant output current.
If this results in the output voltage exceeding the “Output Over-
Voltage Protection” threshold*, then the unit will shut down.
Output Over-Voltage Limit (OVP): 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
500ms the converter will automatically restart for all but the S
Feature Set option, which is latching and will not restart until input
power is cycled or the ON/OFF input is toggled.
Over-Temperature Shutdown (OTP): 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 500 ms when it is
shut down due to a fault. This generates a 2 Hz “hiccup mode,”
which prevents the converter from overheating. In all, there
are three ways that the converter can be shut down, initiating a
Startup Inhibit Period:
• Output Over-Voltage Protection
• Current Limit
• Short Circuit Protection

APPLICATION CONSIDERATIONS
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: For baseplated and encased versions,
the max operating baseplate temperature, TB, is 100ºC. Refer to
the Thermal Derating Curves in the Technical Figures section to
see the available output current at baseplate temperatures below
100ºC.
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 baseplate 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 100ºC.
Application Circuits: A typical circuit diagram, Figure C below
details the input filtering and voltage trimming.
Input Filtering and External Input Capacitance: Figure
D below shows the internal input filter components. This filter
dramatically reduces input terminal ripple current, which otherwise
could exceed the rating of an external electrolytic input capacitor.
The recommended external input capacitance is specified in the
Input Characteristics section of the Electrical Specifications. More
detailed information is available in the application note titled “EMI
Characteristics” on the SynQor website.

diss
This value of maximum power dissipation can then be used in
conjunction with the data shown in the Power Dissipation Curves
in the Technical Figures section to determine the maximum load
current (and power) that the converter can deliver in the given
thermal condition.
Output Filtering and External Output Capacitance: The
internal output filter components are shown in Figure D below.
This filter dramatically reduces output voltage ripple. Some
minimum external output capacitance is required, as specified in
the Output Characteristics area of the Electrical Characteristics
section. No damage will occur without this capacitor connected,
but peak output voltage ripple will be much higher.

ACTIVE CURRENT SHARE
•
Overview: The full-featured option, specified by an “F” in the
last character in the part number, has current sharing operation
supported, achieved by adding two additional pins: SHARE(+) and
SHARE(-).
Connection of Paralleled Units: Up to 100 units can be placed in
parallel. In this current share architecture, one unit is dynamically
chosen to act as a master, controlling all other units. It cannot be
predicted which unit will become the master at any given time, so
units should be wired symmetrically (see Figures E & F).

Application Section
Automatic Configuration: The micro-controller inside each power
converter unit is programmed at the factory with a unique chip number.
In every other respect, each shared unit is identical and has the same
orderable part number.
Resonance Between Output Capacitors is Possible: When
multiple higher-voltage modules are paralleled, it is possible to
excite a series resonance between the output capacitors internal to
the module and the parasitic inductance of the module output pins.
This is especially likely at higher output voltages where the module
internal capacitance is relatively small. This problem is independent
of external output capacitance. For modules with an output voltage
greater than 18 V, to ensure that this resonant frequency is below the
switching frequency it is recommended to add a nominal 470 nH of
inductance, located close to the module, in series with each converter
output. There must be at least 10 μF of capacitance per converter,
located on the load-side of that inductor. The inductance could be from
the leakage inductance of a secondary-side common-mode choke; in
which case the output capacitor should be appropriately sized for the
chosen choke. When using an output common-mode choke, the Sense
lines must be connected on the module-side of the common-mode
choke (see Figure F).
RS-485 Physical Layer: The internal RS-485 transceiver includes
many advanced protection features for enhanced reliability:
• Current Limiting and Thermal Shutdown for
Driver Overload Protection
• IEC61000 ESD Protection to +/- 16.5 kV
• Hot Plug Circuitry – SHARE(+) and SHARE(-)
Outputs Remain Tri-State During Power-up/Power-down
On initial startup (or after the master is disabled or shuts down),
each unit determines the chip number of every other unit currently
connected to the shared serial bus formed by the SHARE(+) and
SHARE(-) pins. The unit with the highest chip number dynamically
reconfigures itself from slave to master. The rest of the units (that do
not have the highest chip number) become slaves.
The master unit then broadcasts its control state over the shared serial
bus on a cycle-by-cycle basis. The slave units interpret and implement
the control commands sent by the master, mirroring every action of
the master unit.
If the master is disabled or encounters a fault condition, all units will
immediately shut down, and if the master unit is unable to restart,
then the unit with the next highest chip number will become master. If
a slave unit is disabled or encounters a fault condition, all other units
continue to run, and the slave unit can restart seamlessly.
Automatic Interleaving: The slave units automatically lock
frequency with the master, and interleave the phase of their switching
transitions for improved EMI performance. To obtain the phase angle
relative to the master, each slave divides 360 degrees by the total
number of connected units, and multiples the result by its rank among
chip numbers of connected units.
Internal Schottky Diode Termination: Despite signaling at high
speed with fast edges, external termination resistors are not necessary.
Each receiver has four Schottky diodes built in, two for each line in the
differential pair. These diodes clamp any ringing caused by transmission
line reflections, preventing the voltage from going above about 5.5 V
or below about -0.5 V. Any subsequent ringing then inherently takes
place between 4.5 and 5.5 V or between -0.5 and 0.5 V. Since each
receiver on the bus contains a set of clamping diodes to clamp any
possible transmission line reflection, the bus does not necessarily need
to be routed as a daisy-chain.
ORing Diodes placed in series with the converter outputs must also
have a resistor smaller than 500 Ω placed in parallel. This resistor
keeps the output voltage of a temporarily disabled slave unit consistent
with the active master unit. If the output voltage of the slave unit
were allowed to totally discharge, and the slave unit tried to restart, it
would fail because the slave reproduces the duty cycle of the master
unit, which is running in steady state and cannot repeat an output
voltage soft-start.
Pins SHARE(+) and SHARE(-) are referenced to Vin(-), and therefore
should be routed as a differential pair near the Vin(-) plane for optimal
signal integrity. The maximum difference in voltage between Vin(-
) pins of all units on the share-bus should be kept within 0.3 V to
prevent steady-state conduction of the termination diodes. Therefore,
the Vin(-) connections to each unit must be common, preferably
connected by a single copper plane.
Share Accuracy: Inside each converter micro-controller, the duty
cycle is generated digitally, making for excellent duty cycle matching
between connected units. Some small duty cycle mismatch is caused
by (well controlled) process variations in the MOSFET gate drivers.
However, the voltage difference induced by this duty cycle mismatch
appears across the impedance of the entire power converter, from
input to output, multiplied by two, since the differential current flows
out of one converter and into another. So, a small duty cycle mismatch
yields very small differential currents, which remain small even when
100 units are placed in parallel.
Common-Mode Filtering must be a single primary side choke handling
the inputs from all the paralleled units, or multiple chokes placed on
the secondary side. This ensurses a solid Vin(-) plane is maintained
between units. Adding a common-mode choke at the output eliminates
the need for the 470 nH indcutor at the output of shared units when
Vout > 18 V. If an output common-mode choke is used, sense
connections must be made on the module-side of the choke.
In other current-sharing schemes, it is common to have a current-
sharing control loop in each unit. However, due to the limited bandwidth
of this loop, units do not necessarily share current on startup or during
transients before this loop has a chance to respond. In contrast, the
current-sharing scheme used in this product has no control dynamics:
control signals are transmitted fast enough that the slave units can
mirror the control state of the master unit on a cycle-by-cycle basis,
and the current simply shares properly, from the first switching cycle
to the last.
