TWR A-Series
s
12-15W, Triple Output DC-DC Converters
Featuring Murata Power Solutions' ultra-wide, 18-72V, input voltage
range, this Family of A-Series, TWR (triple-output) DC-DC converters
deliver up to 15 Watts.
PRODUCT OVERVIEW
Typical units
These devices each have a primary +5V output
that can source from 1 Amp to 1.5 Amps (model
dependent) and auxiliary 12ꢀ15V outputs that can
source from 15ꢁ to 25ꢁmA (model dependent).
All models can simultaneously source maximum
rated current from both primary and auxiliary
outputs. The nominal input voltage for each model
is 48V.
qualification program that includes HALT (Highly-
Accelerated Life Testing), which is designed to
detect any potential electrical, mechanical or proc-
ess weakness.
Packaged in standard, 2" x 2" x ꢁ.45", shielded
metal cases with non-conductive coatings, these
fully isolated (1ꢁꢁꢁVdc minimum) DC-DC’s offer
excellent line and load regulation. Additionally,
these A-Series triples have non-latching output
current limiting, input overvoltage shutdown, input
reverse-polarity protection, and output overvoltage
clamping to protect both the power converters and
their loads. All A-Series TWR models are fully EMI
characterized and designed to meet UL195ꢁ, IEC
95ꢁ, CSA 95ꢁ and EN6ꢁ95ꢁ.
FEATURES
As members of Murata Power Solutions’ new
A-Series, the 12-15W triples exhibit both low cost
and outstanding long-term reliability. Their design
combines straightforward circuit topologies, proven
SMT-on-pcb construction methods, the newest
components, and highly repeatable automatic-
assembly techniques. The A-Series TWR’s superior
durability is substantiated by a rigorous in-house

With Derating
All TWR A-Series 12-15 Watt DC-DC Converters achieve their rated ripple
and noise specifications without the use of external inputꢀoutput capaci-
tors. In critical applications, inputꢀoutput ripple and noise may be further
reduced by installing electrolytic capacitors across the input terminals andꢀ
or low-ESR tantalum or electrolytic capacitors across the output terminals.
Output capacitors should be connected between their respective output pin
(pin 5, 6 or 8) and Common (pin 7) as shown in Figure 2. The caps should
be located as close to the power converters as possible. Typical values are
listed below. In many applications, using values greater than those listed
will yield better results.

These power converters require a minimum 1ꢁ% loading on their primary output and a
minimum 2ꢁ% loading on their auxiliary outputs to maintain specified regulation. Opera-
tion under no-load conditions will not damage these devices; however they may not meet
all listed specifications.
Application-specific internal inputꢀoutput filtering can be recommended and perhaps
added internally upon request. Contact Murato Power Solutions Applications Engineering
for details.
In critical, space-sensitive applications, Murata Power Solutions may be
able to tailor the internal inputꢀoutput filtering of these units to meet your
specific requirements. Contact our Applications Engineering Group for
additional details.
Devices can be screened or modified for higher guaranteed isolation voltages.

Quality and Reliability
Contact us. Our goal is to provide you the highest-quality, most cost-
effective power converters available.
The A-Series are the first DC-DC Converters to emerge from Murata Power
Solutions’ new, company-wide approach to designing and manufacturing
the most reliable power converters available. The five-pronged program
draws our Quality Assurance function into all aspects of new-product
design, development, characterization, qualification and manufacturing.

If you’re designing with EMC in mind, please note that all of Murata Power
Solutions’ TWR A-Series 12-15 Watt DC-DC Converters have been charac-
terized for radiated and conducted emissions in our new EMIꢀEMC labora-
tory. Testing is conducted in an EMCO 53ꢁ5 GTEM test cell utilizing EMCO
automated EMC test software. Radiated emissions are tested to the limits
of FCC Part 15, Class B and CISPR 22 (EN 55ꢁ22), Class B. Correlation to
other specifications can be supplied upon request. Radiated emissions
plots to FCC and CISPR 22 for model TWR-5ꢀ15ꢁꢁ-15ꢀ25ꢁ-D48A appear
below. Published EMC test reports are available for each model number.

Design for Reliability
Design for Reliability is woven throughout our multi-phased, new-product-
development process. Design-for-reliability practices are fully documented
and begin early in the new-product development cycle with the following
goals:
1. To work from an approved componentsꢀvendors list ensuring the use of
reliable components and the rigorous qualification of new components.
2. To design with safety margins by adhering to a strict set of derating
guidelines and performing theoretical worst-case analyses.
3. To locate potential design weaknesses early in the product-development

cycle by using extensive HALT (Highly Accelerated Life Testing).
4. To prove that early design improvements are effective by employing a
thorough FRACA (Failure Reporting Analysis and Corrective Action) system.
Qualification
HALT Testing
For each new product, electrical performance is verified via a comprehensive
characterization process and long-term reliability is confirmed via a rigorous
qualification procedure. The qual procedure includes such strenuous tests as
thermal shock and 5ꢁꢁ hour life. Qual testing is summarized below.
The goal of the accelerated-stress techniques used by Murata Power
Solutions is to force device maturity, in a short period of time, by exposing
devices to excessive levels of "every stimulus of potential value." We use
HALT (Highly Accelerated Life Testing) repeatedly during the design and
early manufacturing phases to detect potential electrical and mechanical
design weaknesses

Max. rated temp., 1,000 hours
10 cycles, –55 to +125°C
During HALT, prototype and pre-production DC-DC converters are subjected
to progressively higher stress levels induced by thermal cycling, rate of
temperature change, vibration, power cycling, product-specific stresses
(such as dc voltage variation) and combined environments. The stresses are
not meant to simulate field environments but to expose any weaknesses
in a product’s electroꢀmechanical design andꢀor assembly processes. The
goal of HALT is to make products fail so that device weaknesses can be
analyzed and strengthened as appropriate. Applied stresses are continu-
ally stepped up until products eventually fail. After corrective actions andꢀ
or design changes, stresses are stepped up again and the cycle is repeated
until the "fundamental limit of the technology" is determined.

Rapid Response to Problems
Murata Power Solutions employs an outstanding corrective-action system
to immediately address any detected shortcomings in either products or
processes. Whenever our assembly, quality or engineering personnel spot
a productꢀprocess problem, or if a product is returned with a potential
defect, we immediately perform a detailed failure analysis and, if necessary,
undertake corrective actions. Over time, this system has helped refine our
assembly operation to yield one of the lowest product defect rates in the
industry.
