UWR Models  
s
Single Output, High-Density,  
6 Amp/15 Watt DC/DC Converters  
ODUCT OVERVIEW  
e new 1.2, 1.5V, 1.8V and 2.5V models in  
rata Power Solutions’ flagship 7-15 Watt  
Series can source a continuous 6 Amps. This  
he most "low-voltage" current available from  
tandard 1" x 2" package, and these power  
nverters exemplify Murata Power Solutions’  
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 output-  
trim 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 low-  
cost, 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.

Single Output, High-Density,  
6 Amp/15 Watt DC/DC Converters  
Floating Outputs  
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.  
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  
Trimming Output Voltages  
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).  
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 depend-  
ing on its connection. Fixed resistors should have an absolute TCR less than  
100ppm/°C to minimize sensitivity to changes in temperature.  
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.  
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.  
Operation under no-load conditions will not damage 12/15V converters.  
However they may not meet all listed specifications.  
Trim adjustment greater than 5% can have an adverse effect on the con-  
verter's performance and is not recommended.  
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.

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.

Figure 3.Trim Connections To Decrease Output Voltage Using Fixed Resistors  
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.

Soldering Guidelines  
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 volt-  
age 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 indetermi-  
nate on/off situations at a single voltage.  
Murata Power Solutions recommends the specifications below when install-  
ing 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.  
Wave Solder Operations for through-hole mounted products (THMT)  
For Sn/Ag/Cu based solders:  
Start-Up Time  
The VIN to VOUT Start-Up Time is the interval between the time at which a ramp-  
ing 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.

115° C.  
270° C.  
7 seconds  
105° C.  
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.

Temperature Derating Curves for UWR 7-15W A-Series  
The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters is  
D24A and D48A Temperature Derating for 1.5V Output Models  
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.

the pin 3 position, with adapted current limit set point to 6.5A min. and with  
removed Input Overvoltage Shutdown function.  
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.
