Figure 1. Simplified Schematic

Featuring DATEL’s ultra-wide, 18-72V , input v oltage range, this new F amily of
A-Series, TWR (triple-output) DC/DC converters deliver up to 15 Watts. These
devices each have a primary +5V output that can source from 1 Amp to 1.8 Amps
(model dependent) and auxiliary ±12/15V outputs that can source from ±150 to
±250mA (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 .

As members of DATEL ’ s new A-Series, the 12-15W triples exhibit both lo w cost
and outstanding long-term reliability. Their design combines straightforw ard 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 qualification program that includes
HAL T (Highly-Accelerated Life Testing), which is designed to detect any potential
electrical, mechanical or process weakness.

Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conductive
coatings, these fully isolated (1000Vdc 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 UL1950,
IEC 950, CSA 950 and EN60950.

Filtering and Noise Reduction

All TWR A-Series 12-15 Watt DC/DC Converters achieve their rated ripple and
noise specifications without the use of external input/output capacitors. In
critical applications, input/output ripple and noise may be further reduced by
installing electrolytic capacitors across the input terminals and/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. T ypical v alues are listed below . In
many applications, using values greater than those listed will yield better
results.

To Reduce Input Ripple 10µF , 100V
To Reduce Output Ripple

+5V Output 47µF, 10V, Low ESR
±12/15V Outputs 22µF , 20V , Low ESR

In critical, space-sensitive applications, DATEL may be able to tailor the
internal input/output filtering of these units to meet your specific requirements.
Contact our Applications Engineering Group for additional details.

➀

These power converters require a minimum 10% loading on their primary output and a
minimum 20% loading on their auxiliary outputs to maintain specified regulation. Operation
under no-load conditions will not damage these devices; however they may not meet all
listed specifications.

➁

Application-specific internal input/output filtering can be recommended and perhaps added
internally upon request. Contact DA TEL Applications Engineering for details.

Devices can be screened or modified for higher guaranteed isolation voltages.

TECHNICAL NOTES

4

If you’re designing with EMC in mind, please note that all of D ATEL’s TWR
A-Series 12-15 Watt DC/DC Converters have been characterized for radiated
and conducted emissions in our new EMI/EMC laboratory . Testing is conducted
in an EMCO 5305 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 55022), Class B. Correlation to other specifications can be
supplied upon request. Radiated emissions plots to FCC and CISPR 22 for
model TWR-5/1800-12/200-D48A appear below . Published EMC test reports
are availab le for each model number. Contact D A TEL’s Applications Engineer­ing Department for more details.

Input Fusing

Certain applications and/or safety agencies may require the installation of fuses
at the inputs of power conversion components . F or D ATEL A-Series TWR 12­15 Watt DC/DC Converters, you should use slow-blow type fuses with values
no greater than 2A.

Quality and Reliability

The A-Series are the first DC/DC Converters to emerge from DATEL ’ s 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.

Design for Reliability

Design for Reliability is woven throughout our multi-phased, new-product­development process. Design-for-reliability practices are fully documented and
begin early in the new-product development cycle with the following goals:

1. T o wo rk from an approved components/vendors 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. T o locate potential design weaknesses early in the product-dev elopment
cycle by using extensive HALT (Highly Accelerated Life Testing).

4. To prove that early design improvements are effectiv e by emplo ying a
thorough FRACA (Failure Reporting Analysis and Corrective Action) system.

HALT T esting

The goal of the accelerated-stress techniques used by DATEL is to force device
maturity , in a short period of time, by exposing devices to e xcessive lev els of
"every stimulus of potential value." We use HALT (Highly Accelerated Life
T esting) repeatedly during the design and early manufacturing phases to detect
potential electrical and mechanical design weaknesses
that could result in possible future field failures.

During HAL T , prototype and pre-production DC/DC con verters 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
electro/mechanical design and/or 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 continually stepped up until products
eventually fail. After corrective actions and/or design changes, stresses are
stepped up again and the cycle is repeated until the "fundamental limit of the

technology" is determined.
DATEL has invested in a Qualmark OVS-1 HALT tester capable of applying

voltage and temperature extremes as well as 6-axis, linear and rotational,
random vibration. A typical HALT profile (shown above) consists of thermal
cycling (–55 to +125°C, 30°C/minute) and simultaneous, gradually increasing,
random longitudinal and rotational vibration up to 20G’s with load cycling and
applied-voltage extremes added as desired. Many devices in D A TEL’s new A­Series could not be made to fail prior to reaching either the limits of the HAL T
chamber or some previously known physical limit of the device. We also use
the HAL T chamber and its ability to rapidly cool devices to v erify their "cold­start" capabilities.

Qualification

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 500 hour life. Qual testing is summarized below .

In-Line Process Controls and Screening

A combination of statistical sampling and 100% inspection techniques keeps
our assembly line under constant control. Parameters such as solder-paste
thickness, component placement, cleanliness, etc. are statistically sampled,
charted and fine tuned as necessary. Visual inspections are perf ormed by
trained operators after pick-and-place, soldering and cleaning operations. Units
are 100% electrically tested prior to potting. All devices are temperature cycled,
burned-in, hi-pot tested and final-electrical tested prior to external visual
examination, packing and shipping.

Rapid Response to Problems

DATEL 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 product/process 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 .
