IQ24-QTC Family
BASIC OPERATION AND FEATURES
CONTROL 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.
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.
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.
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.
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
[Vout(+) - Vout(-)] – [Vsense(+) - Vsense(-)] <
Sense Range % x Vout
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.

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 =
- 10.22
(511
∆% )
(kW)
where
∆% =
Vnominal – Vdesired
Vnominal
x 100%
To increase the output voltage, the user should connect a
resistor between Pin 6 and Pin 7 (SENSE(+) input). For a desired
increase of the nominal output voltage, the value of the resistor
should be
Rtrim-up =
where
(
5.11VOUT x (100+∆%)
1.225∆%
_ 511 _ 10.22
∆%
)
(kW)
Vout = Nominal Output Voltage
Graphs on Page 3 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 over-voltage 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 “0” on our 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 (listed on the specifications 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.
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 CurrentLimit Shutdown Voltage, the converter turns off.
The converter then enters a “hiccup mode” where it repeatedly
turns on and off at a 5 Hz (nominal) frequency with a 5% 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
200 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.

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.
application Circuits: Figure D provides a typical circuit
diagram which details the input filtering and voltage trimming.
Input Filtering and external Capacitance: Figure E provides
a diagram showing 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 on the Electrical Characteristics
page. More detailed information is available in the application
note titled “EMI Characteristics” on the SynQor website.
Startup Inhibit Period: The Startup Inhibit Period ensures that
the converter will remain off for approximately 200 ms when it is
shut down for any reason. When an output short is present, this
generates a 5 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:
• Input Under-Voltage Lockout
• Output Over-Voltage Protection
• Over Temperature Shutdown
• Current Limit
• Short Circuit Protection
• Turned off by the ON/OFF input

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.
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.
When the ON/OFF pin goes high after t2, the Startup Inhibit
Period has elapsed, and the output turns on within the typical
Turn-On Time.
Thermal Considerations: The maximum operating baseplate temperature, TB, is 100 ºC. As long as the user’s thermal
system keeps TB < 100 ºC, the converter can deliver its full
rated power.
maximum power the converter can dissipate for a given thermal
condition if its base-plate is to be no higher than 100 ºC.

Pdiss =
100 ºC - TA
RTHBA
This value of power dissipation can then be used in conjunction
with the data shown in Figure 2 to determine the maximum load
current (and power) that the converter can deliver in the given
thermal condition.
For convenience, Figures 3 and 4 provide Power derating curves
for an encased converter without a heatsink and with a typical
1/4" high heatsink.
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 the be used to determine the
