Single Output
A-Series, UWR Models
High-Density, 1" x 2"
6 Amp/15 Watt, 1.2-15VOUT DC/DC's
A - S E R I E S
The new 1.2, 1.5V, 1.8V and 2.5V models in DATEL’s 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 DATEL’s
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, 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 certified to IEC950, UL1950 and
EN60950 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.

Trimming OutputVoltages
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 depending
on its connection. Fixed resistors should have an absolute TCR less than
100ppm/°C to minimize sensitivity to changes in temperature.
Floating Outputs
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.
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.
Minimum Output Loading Requirements
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).
Trim adjustment greater than 5% can have an adverse effect on the convert-
er's performance and is not recommended.
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.

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 volt-
age ratings and be mounted 2-3 inches from the converter to achieve
published ratings.

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 DATEL A-Series UWR 7-15 Watt DC/DC Converters, you
should use slow-blow type fuses with values no greater than the following.

Start-UpThreshold 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
indeterminate on/off situations at a single voltage.
Start-UpTime
The VIN to VOUT Start-Up Time is the interval between the time at which
a ramping 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.
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.

The thermal performance of A-Series UWR 7-15 Watt DC/DC Converters
is 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. Contact
DATEL's Applications Engineering Group if you need additional details.

There are various additional configurations available on A-Series 7-15W
DC/DC's. Because designating each of them with a standard part-number
suffix would result in an unmanageable matrix of part numbers, such are
designated by DATEL and assigned 5-digit "part-number suffixes. Once a
configuration has been requested by a customer and created by DATEL, the
resulting product is available to any customer as a "standard" off-the-shelf
product. Consequently, the following products are offered for sale:

Optional Functions
The A-Series 7-15W DC/DC Converters offer numerous electrical/ mechani-
cal 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.
Standard product, 48VIN, 5VOUT/3A. On/Off Control function (positive polarity)
on pin 3, VOUT, Trim function added on pin 5. Adaptations:Trim equations are
Tyco/Lucent-compatible.Transformer isolation system has been enhanced to
meet the BASIC INSULATION requirements of UL60950/EN60950. I/O pins
are 25-mil-square Tyco/Lucent compatible. Shielded metal case is connected
to +VIN pin 1. Input Overvoltage Shutdown function has been removed.
RoHS-5 compliance refers to the exclusion of the six hazardous substances
in the RoHS specification with the excepion of lead. C&D Technologies'
RoHS-5 products use all the conforming RoHS materials, however our
solders are Sn63/Pb37.
