The new 1.2, 1.5V, 1.8V and 2.5V models in
Murata
Power Solutions’ flagship 7-15 Watt
Mu
A-Series
can source a continuous 6 Amps. This
A-S
is the
t most "low-voltage" current available from
a standard
1" x 2" package, and these power
s
converters
exemplify Murata Power Solutions’
con
relentless drive to bring you more power/current,
from standard packages, without compromising
reliability or resorting to thermal specmanship.
By combining a high-frequency, high-efficiency
(to 88%), synchronous-rectifier topology with
the newest components and time-tested, fully
automated, SMT-on-pcb construction, these
UWR Models are able to bring you 7-15W (@
up to 6A) in the standard 1" x 2" package from
which most competitors can only get 5-10W (@
3-4A). All UWR’s deliver their full output power
over ambient temperature ranges from –40°C
to as high as +70°C (model and input voltage
dependent) without heat sinks or supplemental
forced-air cooling. Devices derate to +100°C.
Output voltages are 1.2, 1.5, 1.8, 2.5, 3.3, 5,
12 or 15 Volts. Input voltage ranges are 10-18V
(D12 models), 18-36V (D24 models) or 36-75V
(D48 models). All models feature input pi filters,
input undervoltage and overvoltage lockout, input
reverse-polarity protection, output overvoltage
protection, output current limiting, and continuous
short-circuit protection. On/off control and outputtrim functions are optional (see Optional Functions).
All models are designed to meet IEC950, UL1950
and EN60950-1, 2nd Edition safety requirements.
D48 models (36-75V inputs) are CE marked.
UWR 7-15W DC/DC’s are packaged in lowcost, light-weight, diallyl phthalate (UL94V-0
rated) plastic packages with standoffs. EMC
compliance is achieved via a low-noise design
rather than through expensive metal shielding.

UWR Models
Single Output, High-Density,
6 Amp/15 Watt DC/DC Converters
Floating Outputs
Since these are isolated DC/DC converters, their outputs are "floating."
Designers will usually use the output Common (pin 6) as the ground/return of
the load circuit. You can, however, use the +Output (pin 4) as ground/return to
effectively reverse the output polarity.
Minimum Output Loading Requirements
1.2 to 5V models employ a synchronous-rectifier design topology. All models
regulate within spec and are stable under no-load conditions. 12/15V models
employ a traditional forward architecture and require 10% loading (125mA for
12V models, 100mA for 15V models) to achieve their listed regulation specs.
12/15V models also have a minimum-load-for-stability requirement (20mA).
For 12/15V models, operation below 20mA or 10% loading will be stable but
regulation may degrade. A 100μF output capacitor is recommended below 10%
loading. Users should verify whether this relaxed regulation will have any effect
on output circuits. If so, add a small load of 10% or greater.
Operation under no-load conditions will not damage 12/15V converters.
However they may not meet all listed specifications.
Filtering and Noise Reduction
All A-Series UWR DC/DC Converters achieve their rated ripple and noise
specifications using the external input and output capacitors specified in the
Performance/Functional Specifications table. In critical applications, input/
output noise may be further reduced by installing additional external I/O caps.
Input capacitors should be selected for bulk capacitance, low ESR and high
rms-ripple-current ratings. Output capacitors should be selected for low ESR and
appropriate frequency response. All caps should have appropriate voltage ratings
and be mounted 2-3 inches from the converter to achieve published ratings. The
most effective combination of external I/O capacitors will be a function of your
particular load and layout conditions.
red camera is a another alternative which avoids the TC heatsinking effect.
But the IR camera must be calibrated frequently and accurately. Remember
too that it is quite difficult to accurately measure airflow right at the converter.
Murata Power Solutions uses a calibrated wind tunnel with large amounts
of data history. Because of thermal time constants, allow plenty of time for
temperature stabilization.
Trimming Output Voltages
These converters have a trim capability (pin 5) that allows users to adjust the
output voltage ±5%. Adjustments to the output voltage can be accomplished
via a trim pot, Figure 2, or a single fixed resistor as shown in Figures 3 and 4.
A single fixed resistor can increase or decrease the output voltage depending on its connection. Fixed resistors should have an absolute TCR less than
100ppm/°C to minimize sensitivity to changes in temperature.
A single resistor connected from the Trim (pin 5) to the +Output (pin 4), see
Figure 3, will decrease the output voltage. A resistor connected from the Trim
(pin 5) to Output Common (pin 6) will increase the output voltage.
Trim adjustment greater than 5% can have an adverse effect on the converter's performance and is not recommended.

Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. Fuses should also be
used if the possibility of sustained, non-current-limited, input-voltage polarity
reversals exists. For MPS's A-Series UWR 7-15 Watt DC/DC Converters, you
should use fast-blow type fuses with values no greater than the following.

Maximum Case Temperature
The +100 degree C. maximum outside case temperature specification is based
on much empirical testing on encapsulated units. Those tests show that if
the case exterior can be maintained at or below +100C., the hottest internal
components’ package temperatures will not exceed +128C. because of the
internal temperature gradient to the exterior case. This latter +128C. internal
figure is a safety margin offering more protection for the internal components.
The +100C. case specification must be achieved by the user’s combination of
lower output current and/or higher airflow.
If you attempt any of your own case temperature testing, please be aware of
the heatsinking effect of attaching wired thermocouples to surfaces. An infra-

Soldering Guidelines
Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type.
Exceeding these specifications may cause damage to the product. Be cautious
when there is high atmospheric humidity. Your production environment may
differ; therefore please thoroughly review these guidelines with your process
engineers.

Start-Up Threshold and Undervoltage Shutdown
Under normal start-up conditions, devices will not begin to regulate until the
ramping-up input voltage exceeds the Start-Up Threshold Voltage (35V for
"D48A" models). Once operating, devices will not turn off until the input voltage drops below the Undervoltage Shutdown/Lockout limit (34V for "D48A"
models). Subsequent re-start will not occur until the input is brought back up to
the Start-Up Threshold. This built-in hysteresis obviously avoids any indeterminate on/off situations at a single voltage.
Wave Solder Operations for through-hole mounted products (THMT)
For Sn/Ag/Cu based solders:
Maximum Preheat Temperature
115° C.
Maximum Pot Temperature

Maximum Solder Dwell Time
6 seconds
Start-Up Time
The VIN to VOUT Start-Up Time is the interval between the time at which a ramping input voltage crosses the turn-on threshold point 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, and the
slew rate and final value of the input voltage as it appears to the converter.
The On/Off to VOUT Start-Up Time assumes the converter is turned off via the
On/Off Control with the nominal input voltage already applied to the converter.
The specification defines the interval between the time at which the converter
is turned on and the fully-loaded output voltage enters and remains within its
specified accuracy band.
Accuracy of adjustment is subject to tolerances or resistor values and
factory-adjusted output accuracy. VO = desired output voltage.

Output Power (Watts)
The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters is
depicted in the derating curves shown below. All devices, when operated at full
load, in still ambient air, over their full specified input voltage range, can safely
operate to TA maximum. All models, other than the D12A models (10-18 Volt
input range), can operate at higher ambient temperatures if the input range is
narrowed. For example, model UWR-5/3000-D48A can operate safely to +70°C
if the input range is kept between 36 and 48 Volts.

Optional Functions
The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechanical
options. Per the Ordering Guide on page 2, the trailing "A" (A-Series) in each
part number pertains to the base part number. Part-number suffixes are added
after the "A," indicating the selection of standard options. The resulting part
number is a "standard product" and is available to any customer desiring that
particular combination of options. As described below, selecting certain options
will result in the installation of additional pins in certain locations.
* Note: Usage of consecutive "C" and "-C" designations is correct for some
models. Example: UWR-5/3000-D48AC-C
Adaptations
There are various additional configurations available on A-Series 7-15W DC/DCs.
Because designating each of them with a standard part-number suffix would
result in an unmanageable matrix of part numbers, such are designated by
MPS and assigned 5-digit "part-number suffixes.
