Typical units

PRODUCT OVERVIEW

The new 1.2, 1.5V, 1.8V and 2.5V models in

Murata Power Solutions’ ﬂagship 7-15 Watt

A-Series can source a continuous 6 Amps. This

is the most "low-voltage" current available from

a standard 1" x 2" package, and these power

converters 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.

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.

Certain applications and/or safety agencies may require the installation of

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.

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.

105° C.

The On/Off to V^OUTStart-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.

250° C.

6 seconds

Accuracy of adjustment is subject to tolerances or resistor values and

factory-adjusted output accuracy. V^O= 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 T^Amaximum. 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.
