– 160 Vdc in an industry standard quarter
brick fully encased package at astonishing
efficiency. The fully isolated (3000Vdc) IRQ
series accept a 57.6 to 160 Volt DC input
voltage range with a reinforced insulation
system. Typical applications include
industrial, railway and transportation
applications.
The IRQ’s synchronous-rectifier topology and
fixed frequency operations means excellent
efficiencies. A wealth of electronic protection
features include input under voltage lockout,
over voltage lockout protection, output
current limit, current sharing, short circuit
hiccup, Vout overshoot, and over temperature
shutdown.
Available options include various pin lengths
and flanged baseplate. The IRQ series is
designed to meet all UL and IEC emissions,
safety, and flammability certifications.

Technical Notes
On/Off Control
The input-side, remote On/Off Control function (pin 2) can be ordered to
operate with either logic type:
Negative (“N” suffix): Negative-logic devices are off when pin 2 is left
open (or pulled high, applying +3.5V to +13V), and on when pin 2 is
pulled low (0 to 0.8V) with respect to –Input as shown in Figure 1.
+VIN
–VIN
Figure 1. Driving the Negative Logic On/Off Control Pin
Dynamic control of the remote on/off function is best accomplished
with a mechanical relay or an open-collector/open-drain drive circuit
(optically isolated if appropriate). The drive circuit should be able to sink
appropriate current (see Performance Specifications) when activated and
withstand appropriate voltage when deactivated. Applying an external
voltage to pin 2 when no input power is applied to the converter can
cause permanent damage to the converter.
Input Fusing
Certain applications and/or safety agencies may require fuses at the
inputs of power conversion components. Fuses should also be used when
there is the possibility of sustained input voltage reversal which is not
current-limited. For greatest safety, we recommend a fast blow fuse
installed in the ungrounded input supply line.

These converters include a soft start circuit to moderate the duty
cycle of its PWM controller at power up, thereby limiting the input inrush
current.
The On/Off Remote Control interval from On command to Vout (final
±5%) assumes that the converter already has its input voltage stabilized
above the Start-Up Threshold before the On command. The interval is
measured from the On command until the output enters and remains
within its specified accuracy band. The specification assumes that the
output is fully loaded at maximum rated current. Similar conditions apply
to the On to Vout regulated specification such as external load
capacitance and soft start circuitry.

Vout Start-Up Time (see Specifications) is the time interval between the
point when the rising input voltage crosses the Start-Up Threshold and
the fully loaded output voltage enters and remains within its specified
accuracy band. Actual measured times will vary with input source
impedance, external input capacitance, input voltage slew rate and final
value of the input voltage as it appears at the converter.
-Vout
Figure 2. Input Fusing
Input Under-Voltage Shutdown and Start-Up Threshold
Under normal start-up conditions, converters will not begin to regulate
properly until the rising input voltage exceeds and remains at the Start-Up
Threshold Voltage (see Specifications). Once operating, converters will
not turn off until the input voltage drops below the Under-Voltage
Shutdown Limit. Subsequent restart will not occur until the input voltage
rises again above the Start-Up Threshold. This built-in hysteresis prevents
any unstable on/off operation at a single input voltage.
Recommended Input Filtering
The user must assure that the input source has low AC impedance to
provide dynamic stability and that the input supply has little or no
inductive content, including long distributed wiring to a remote power
supply. The converter will operate with no additional external capacitance
if these conditions are met.
For best performance, we recommend installing a low-ESR capacitor
immediately adjacent to the converter’s input terminals. The capacitor
should be a ceramic type such as the Murata GRM32 series or a polymer
type. Make sure that the input terminals do not go below the
undervoltage shutdown voltage at all times. More input bulk capacitance
may be added in parallel (either electrolytic or tantalum) if needed.
Recommended Output Filtering
The converter will achieve its rated output ripple and noise with no
additional external capacitor. However, the user may install more external
output capacitance to reduce the ripple even further or for improved
dynamic response. Again, use low-ESR ceramic (Murata GRM32 series)
or polymer capacitors. Mount these close to the converter. Measure the
output ripple under your load conditions.
Use only as much capacitance as required to achieve your ripple and
noise objectives. Excessive capacitance can make step load recovery
sluggish or possibly introduce instability. Do not exceed the maximum
rated output capacitance listed in the specifications.
Input Ripple Current and Output Noise
All models in this converter series are tested and specified for input
reflected ripple current and output noise using designated external
input/output components, circuits and layout as shown in the figures
below. The Cbus and Lbus components simulate a typical DC voltage bus.
Output Over-Voltage Protection
The IRQ output voltage is monitored for an over-voltage condition using a
comparator. The signal is optically coupled to the primary side and if the
output voltage rises to a level which could be damaging to the load, the
sensing circuitry will power down the PWM controller causing the output
voltage to decrease. Following a time-out period the PWM will restart,
causing the output voltage to ramp to its appropriate value. If the fault
condition persists, and the output voltage again climbs to excessive
levels, the over-voltage circuitry will initiate another shutdown cycle. This
on/off cycling is referred to as “hiccup” mode.

Murata Power Solutions makes Characterization measurements in a
closed cycle wind tunnel with calibrated airflow. We use both
thermocouples and an infrared camera system to observe thermal
performance. As a practical matter, it is quite difficult to insert an
anemometer to precisely measure airflow in most applications.
Sometimes it is possible to estimate the effective airflow if you thoroughly
understand the enclosure geometry, entry/exit orifice areas and the fan
flow rate specifications.

Output Fusing
The converter is extensively protected against current, voltage and
temperature extremes. However your output application circuit may need
additional protection. In the extremely unlikely event of output circuit
failure, excessive voltage could be applied to your circuit. Consider using
an appropriate fuse in series with the output.

Minimum Output Loading Requirements
All models regulate within specification and are stable under no load to
full load conditions. Operation under no load might however slightly
increase output ripple and noise.
Thermal Shutdown
To prevent many over temperature problems and damage, these
converters include thermal shutdown circuitry. If environmental
conditions cause the temperature of the DC-DC’s to rise above the
Operating Temperature Range up to the shutdown temperature, an onboard electronic temperature sensor will power down the unit. When the
temperature decreases below the turn-on threshold, the converter will
automatically restart. There is a small amount of hysteresis to prevent
rapid on/off cycling.
CAUTION: If you operate too close to the thermal limits, the converter
may shut down suddenly without warning. Be sure to thoroughly test your
application to avoid unplanned thermal shutdown.
Temperature Derating Curves
The graphs in this data sheet illustrate typical operation under a variety of
conditions. The Derating curves show the maximum continuous ambient
air temperature and decreasing maximum output current which is
acceptable under increasing forced airflow measured in Linear Feet per
Minute (“LFM”). Note that these are AVERAGE measurements. The
converter will accept brief increases in current or reduced airflow as long
as the average is not exceeded.
Note that the temperatures are of the ambient airflow, not the
converter itself which is obviously running at higher temperature than the
outside air.
Output Current Limiting
Current limiting inception is defined as the point at which full power
falls below the rated tolerance. See the Performance/Functional
Specifications. Note particularly that the output current may briefly rise
above its rated value in normal operation as long as the average output
power is not exceeded. This enhances reliability and continued operation
of your application. If the output current is too high, the converter will
enter the short circuit condition.
Output Short Circuit Condition
When a converter is in current-limit mode, the output voltage will drop as
the output current demand increases. If the output voltage drops too low
(approximately 97% of nominal output voltage for most models), the PWM
controller will shut down. Following a time-out period, the PWM will
restart, causing the output voltage to begin rising to its appropriate value.
If the short-circuit condition persists, another shutdown cycle will initiate.
This rapid on/off cycling is called “hiccup mode.” The hiccup cycling
reduces the average output current, thereby preventing excessive internal
temperatures and/or component damage.
The “hiccup” system differs from older latching short circuit systems
because you do not have to power down the converter to make it restart.
The system will automatically restore operation as soon as the short
circuit condition is removed.
Output Capacitive Load
These converters do not require external capacitance added to achieve
rated specifications. Users should only consider adding capacitance to
reduce switching noise and/or to handle spike current load steps. Install
only enough capacitance to achieve noise objectives. Excess external
capacitance may cause degraded transient response and possible
oscillation or instability.

IRQ Series
Remote Sense Input
Use the Sense inputs with caution. Sense is normally connected at the
load. Sense inputs compensate for output voltage inaccuracy delivered at
the load. This is done by correcting IR voltage drops along the output
wiring and the current carrying capacity of PC board etch. This output
drop (the difference between Sense and Vout when measured at the
converter) should not exceed 0.5V. Consider using heavier wire if this
drop is excessive. Sense inputs also improve the stability of the converter
and load system by optimizing the control loop phase margin.
NOTE: The Sense input and power Vout lines are internally connected
through low value resistors to their respective polarities so that the
converter can operate without external connection to the Sense.
Nevertheless, if the Sense function is not used for remote regulation, the
user should connect +Sense to +Vout and –Sense to –Vout at the
converter pins.
The remote Sense lines carry very little current. They are also
capacitively coupled to the output lines and therefore are in the feedback
control loop to regulate and stabilize the output. As such, they are not low
impedance inputs and must be treated with care in PC board layouts.
Sense lines on the PCB should run adjacent to DC signals, preferably
Ground. In cables and discrete wiring, use twisted pair, shielded tubing or
similar techniques.
Any long, distributed wiring and/or significant inductance introduced
into the Sense control loop can adversely affect overall system stability. If
in doubt, test your applications by observing the converter’s output
transient response during step loads. There should not be any
appreciable ringing or oscillation. You may also adjust the output trim
slightly to compensate for voltage loss in any external filter elements. Do
not exceed maximum power ratings.
Contact and PCB resistance
losses due to IR drops
Trimming the Output Voltage
The Trim input to the converter allows the user to adjust the output
voltage over the rated trim range (please refer to the Specifications). In
the trim equations and circuit diagrams that follow, trim adjustments use
either a trimpot or a single fixed resistor connected between the Trim
input and either the +Sense or –Sense terminals. Trimming resistors
should have a low temperature coefficient (±100 ppm/deg.C or less) and
be mounted close to the converter. Keep leads short. If the trim function
is not used, leave the trim unconnected. With no trim, the converter will
exhibit its specified output voltage accuracy.
There are two CAUTIONs to observe for the Trim input:
CAUTION: To avoid unplanned power down cycles, do not exceed
EITHER the maximum output voltage OR the maximum output power
when setting the trim. Be particularly careful with a trimpot. If the output
voltage is excessive, the OVP circuit may inadvertantly shut down the
converter. If the maximum power is exceeded, the converter may enter
current limiting. If the power is exceeded for an extended period, the
converter may overheat and encounter overtemperature shut down.
CAUTION: Be careful of external electrical noise. The Trim input is a
senstive input to the converter’s feedback control loop. Excessive
electrical noise may cause instability or oscillation. Keep external
connections short to the Trim input. Use shielding if needed.

Vnom is the nominal, untrimmed output voltage.
Vout is the desired new output voltage.
Do not exceed the specified trim range or maximum power ratings when adjusting trim.
Use 1% precision resistors mounted close to the converter on short leads.
If sense is not installed, connect the trim resistor to the respective Vout pin.

Please observe Sense inputs tolerance to avoid improper operation:
Trim Circuits
[Vout(+) −Vout(-)] − [Sense(+) −Sense(-)] ≤ 10% of Vout
Output overvoltage protection is monitored at the output voltage pin, not
the Sense pin. Therefore excessive voltage differences between Vout and
Sense together with trim adjustment of the output can cause the
overvoltage protection circuit to activate and shut down the output.
Power derating of the converter is based on the combination of maximum
output current and the highest output voltage. Therefore the designer
must insure:

Vertical Wind Tunnel
Murata Power Solutions employs a computer controlled
custom-designed closed loop vertical wind tunnel, infrared
video camera system, and test instrumentation for accurate
airflow and heat dissipation analysis of power products.
The system includes a precision low flow-rate anemometer,
variable speed fan, power supply input and load controls,
temperature gauges, and adjustable heating element.
The IR camera monitors the thermal performance of the
Unit Under Test (UUT) under static steady-state conditions. A
special optical port is used which is transparent to infrared
wavelengths.
Both through-hole and surface mount converters are
soldered down to a 10"x10" host carrier board for realistic
heat absorption and spreading. Both longitudinal and transverse airflow studies are possible by rotation of this carrier
Heating
board since there are often significant differences in the heat
element
dissipation in the two airflow directions. The combination of
adjustable airflow, adjustable ambient heat, and adjustable
Input/Output currents and voltages mean that a very wide
range of measurement conditions can be studied.
The collimator reduces the amount of turbulence adjacent
to the UUT by minimizing airflow turbulence. Such turbulence influences the effective heat transfer characteristics
and gives false readings. Excess turbulence removes more
heat from some surfaces and less heat from others, possibly
causing uneven overheating.
Both sides of the UUT are studied since there are different thermal gradients on each side. The adjustable heating
element and fan, built-in temperature gauges, and no-contact
IR camera mean that power supplies are tested in real-world
conditions.
