14-20 Watt, DC/DC Converters

DATEL's new A-Series switching DC/DC converters are designed to meet
the demanding long-term-reliability and low-cost requirements of modern telecom,
datacom, computer/networking and industrial-electronics applications. These highly­efficient, rugged devices combine straightforward circuit topologies, new components,
proven SMT-on-pcb construction methods, and highly repeatable automatic-assembly
techniques. The flexibility of the designs and their assembly methods readily permit
minor modifications to optimize performance for specific applications.

The single-output, 14-20 Watt Models of the A-Series deliver both high power
densities and impressive MTBF’s. Their superior durability is substantiated by a
rigorous in-house qualification program including HALT (Highly Accelerated Life Test
ing), which is designed to detect any potential electrical, mechanical, or process
weaknesses.

Packaged in standard, 2" x 2" x 0.45", shielded metal cases with non-conductive
coatings, these fully isolated (1500Vdc minimum) DC/DC’s offer excellent line/load
regulation, full I/O protection, thermal shutdown, and industry-standard pinouts.

Output voltages include 3.3, 5, 5.2, 12 or 15 Volts. Input voltage ranges are
DATEL's traditional ultra-wide 9-36V and 18-75V, as well as 4.7-7.5V. Each device
provides remote on/off control and V

OUT trim capability. All A-Series UWR models are

fully EMI characterized and UL1950, CSA 950 and IEC 950 safety approved.

A-Series DC/DC’s are extremely reliable, easy-to-use, cost-effective power con
verters. Use them to improve the reliability of existing equipment or to develop
new systems that exceed design objectives.

Floating Outputs

Since these are isolated DC/DC converters, their outputs are "floating."
Users may ground either the Common (pin 7) for normal usage or the
positive side (+Output, pin 6) to effectively reverse the output polarity.

Filtering and Noise Reduction

All A-Series UWR 14-20 Watt DC/DC Converters achieve their rated ripple
and noise specifications without the use of external input/output capacitors.
In critical applications, input/output 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. 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.

To Reduce Input Ripple

D5A Models 47µF, 16V
D12A Models 20µF, 50V
D48A Models 20-50µF, 100V

To Reduce Output Ripple

3.3V Outputs 100µF, 6V, Low ESR
5V/5.2V Outputs 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 require

Input Fusing

Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL A-Series
UWR 14-20 Watt DC/DC Converters, you should use slow-blow type fuses
with values no greater than the following:

VIN Range Fuse Value
D5A 6A
D12A 4A
D48A/D48E 2A

On/Off Control

The On/Off Control pin (pin 4) may be used for remote on/off operation. A
TTL logic high (+2 to +5 Volts, 250µA max.) applied to pin 4 disables the
converter. A TTL logic low (0 to +0.8 Volts, 70µA max.), or no connection,
enables the converter. Control voltages should be referenced to pin 2
(–Input). Applying a voltage to the Control pin when no input power is applied
to the converter can cause permanent damage to the converter.

Synchronization

In critical applications employing multiple switching DC/DC converters, it may
be desirable to intentionally synchronize the switching of selected converters
(so the system noise can be reduced with notch filtering) or to purposely
desynchronize the converters (to lessen the current-carrying requirements on
intermediate dc buses). For multiple A-Series Converters, an external clock
can be applied to pin 4 (Control) of each device. It should be a square wave
with a maximum 1µsec "high" duration and an amplitude between +2V and
+5V (see On/Off Control) referenced to pin 2 (–Input). The frequency of the
synchronizing clock should be higher than that of any individual converter.
Therefore, it should be 185kHz ±5kHz.

UWR Models

Figure 2a. Trim Connections Using a Trimpot

Figure 2b. Trim Connections Using Fixed Resistors

Output Trimming

VOUT may be trimmed ±5% via a single external trimpot or fixed resistor. The
trimpot should be connected as shown in Figure 2a with its wiper connected
to pin 8 (Trim). A trimpot can be used to determine the value of a single
fixed
resistor which should be connected as shown in Figure 2b. Connect the
resistor between pin 8 (Trim) and pin 6 (+Output) to trim "down" the output
voltage. Connect the resistor between pins 8 and 7 (Common) to trim "up"
the output voltage. Fixed resistors should be metal-film types with absolute
TCR’s less than 100ppm/°C to ensure stability.

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. To work 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. 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.

HALT Testing

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 excessive
levels of "every stimulus of potential value." We use HALT (Highly Acceler

­ated Life Testing) 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 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 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.

Typical HALT Profile

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 increas

­ing, random longitudinal and rotational vibration up to 20G’s with load cycling
and applied-voltage extremes added as desired. Many devices in DATEL’s
new A-Series could not be made to fail prior to reaching either the limits of
the HALT chamber or some previously known physical limit of the device.
We also use the HALT chamber and its ability to rapidly cool devices to verify
their "cold-start" 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 performed 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. When

­ever 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.
