UWR-2.5/6000-D12ANL2-Y

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.

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 V^INto 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 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.

Accuracy of adjustment is subject to tolerances or resistor values and

factory-adjusted output accuracy. V^O= 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 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. 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, V^OUT,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.

Sufﬁx Description

Blank No VOUT Trim or On/Off Control functions added (no I/O pins

installed in the pin 3 and pin 5 positions).The pin length remains at

0.2 inches (5.08 mm).
