CONTROL FEATURES
BASIC OPERATION AND FEATURES
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.
Both the first stage and the second stage switch at
a fixed frequency for predictable EMI performance.
The switching frequency of second stage is half of the
swithcing frequency of first stage and locked in phase.
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.
These converter 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 use the industry standard footprint
and pin-out configuration.

ON/OFF: The ON/OFF inputs, Pins 3 and 4, permits the
user to turn the converter on or off. These two inputs
are fully isolated from both the input and the output side
of the power converter, allowing the user the option to
manage the converter from the input or the output end.
The user’s on/off control signal is applied between the
ON/OFF(+) pin and the ON/OFF(-) pins. Figure A details
two possible circuits for driving the ON/OFF pin. Figure
B is a detailed look of the internal ON/OFF circuitry.
REMOTE SENSE(+) and SENSE(-) (Pins 11 and 12):
The SENSE inputs correct for voltage drops along the
conductors that connect the converter’s output pins to the
load. Pin 11 should be connected to Vout(+) and Pin 12
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
[Vout(+) - Vout(-)] – [Vsense(+) - Vsense(-)] ≤

Pins 11 and 12 must be connected

are not made, the converter will deliver

connections
an output
set value.
The voltage at the output terminals of the module will be
trimmed up by the control circuit to compensate for voltage
drops between the output pins of the module and the remote
sense point. Note that the over-voltage protection (OVP)
circuit senses the voltage at the output pins of the module.
It is possible to inadvertently trip the OVP protection circuit
if the voltage drop between the output pins and the sense
point becomes too large. Hence, the remote sensing feature
should be used only to compensate for small values of voltage
drops to avoid triggering OVP due to a line or load transient.

OUTPUT VOLTAGE TRIM (Pin 10): 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 10 and Pin 12 (SENSE(-) ). 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 10 (TRIM) and Pin 11 (SENSE(+) ). 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(Fig.3, Fig4 and Fig5) show the relationship
between the trim resistor value and Rtrim-up and Rtrimdown, 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.Note that if the unit is started
at no load the output voltage may, under some conditions,
regulate above its rated value. This condition will be
corrected once the load is increased above 1%, and it will
stay corrected even if the load is lowered to zero.

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 E.
Output Current Limit: The output current 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 “auto-restart” mode where it
repeatedly turns on and off at a 2.5 Hz (nominal) frequency
until the overload 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. For example,
when an output short is present the module will shutdown,
remain off for the startup inhibit period, and then
attempt to restart. This results in a 2.5Hz auto restart
mode of operation which prevents the converter from
overheating. In all, there are seven ways that the converter

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:

Figure E shows three turn-on scenarios, where a Startup

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.

cannot be enabled again until the Startup Inhibit Period has

Full-Featured Application Notes
This section provides some basic application information for
the full-feature version of the InQor 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 the rated
output voltage of the converter.
In addition to back-drive protection, these units include the
following features (pins):
I Share (pin 9)-Active Current Share: Some applications
benefit from connecting the outputs of multiple converters
in parallel. Typical applications include systems that require
power levels higher than the rated power of one converter,
or systems that require N+1(less than 30) redundancy for
increased reliability and availability. The active current share
feature of the IQ4H Full Brick is a secondary side referenced
circuit that ensures that modules configured to operate in
parallel will share load current to a significant degree (±5%
typical at full rated current). This feature is implemented
by directly connecting the I share pins and the Start Sync
pins of multiple units together. Note also that it is important
to connect the SENSE(+) and SENSE(-) pins of each of the
parallel modules in the same physical location to ensure
the most accurate level of current sharing. The voltage at
the I Share pin will range from approximately 1volt (at no
load) to 2.2 volts (at full rated current), referenced to the
secondary-side ground, VSENSE(-). For best performance
in current shared mode,the following connections must be
implemented:
• I share pins of multiple units must be connected together.
• Start Sync pins of multiple units must be connected
together (see details below)
• SENSE(+) and SENSE(-) pins of each module must be tied
together at the same physical location, preferably at the end
of power out cable or trace.
Start Sync (pin 8) - Start Synchronization:The Start
Synchronization feature is a secondary side referenced
circuit that will allow a more consistent start-up sequence
when the output of multiple modules are connected in
parallel. To operate this feature, connect together the StartSync 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
go into an auto-restart mode of operation that 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 sequence. For details about the auto-restart
mode or repeated startup attempts, please see the “Startup
Inhibit Period” note in the Technical Specification.
SyncIn (pin 1) – External Clock Synchronization:
The Clock Synchronization is a primary side referenced
feature which allows 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
within the limits specified in the IQ4H-FT Family Electrical
Characteristics Table. Note that increasing the converter’s
frequency will tend to reduce efficiency.
The Clock Synchronization feature allows the user the
following choices:
• Change the switching frequency of the converter from the
factory pre-set value to a value in the specified range.
• Synchronize the switching of all converters in a current
shared mode to a common external frequency.
• Improve susceptibility of an adjacent sensitive circuit
by moving the converter frequency away from its most
