UPB Models

High-Efficiency, Smaller-Package

25-40 Watt, DC/DC Converters

Features DATEL’s new UPB Model, 25-40 Watt, single-output DC/DC power converters

bring you efficient "on-board" power processing in a cost-effective smaller package
with a standard pinout. The 2" x 3" UPB "footprint" conforms with the industry­standard pinout and pin geometries of most 3" x 3" devices (a 33% space savings)
while delivering as much as 60% more power (40W vs. 25W).

Applicable to a wide range of telecom, computer and other OEM applications,
UPB Model DC/DC’s operate from four input voltage ranges (10-36V for "Q12"
models, 18-36V for "D24" models, 18-72V for "Q48" models, and 36-72V for "D48"
models). Available output voltages are 5, 12 and 15 Volts.

For improved reliability and affordability, DATEL exploits contemporary, high­speed, automatic-assembly techniques to construct the UPB’s traditional, field­proven, SMT-on-pcb designs. Devices employ corrosion-resistant steel cases with
heavy zinc top plates (traditionally referred to as baseplates). Heat generating
transformer cores and power semiconductors are mounted directly to the
baseplates, which also have threaded inserts for optional add-on heat sinks or pcb
mounting. Temperature derating information is provided for operation with and
without heat sinks and forced air flow.

All devices feature input pi filters, input undervoltage and overvoltage shutdown,
output overvoltage protection, output current limiting, and thermal shutdown. All
UPB models are UL1950, CSA 22.2 No. 950, and IEC950 approved. Most ha ve
been EMI/EMC characterized. Contact DATEL for the latest available information.

UPB DC/DC Converters are classified, by output power, into 25, 30, 35 and
40 Watt devices. For any given device, the maximum available output power
is the product of the nominal output voltage and the maximum output current
indicated within the part number. A UPB-5/6-Q48, for example, can source 6
Amps from its 5V output (over its entire 18-72V input range) delivering an
output power of 30 Watts. A UPB-5/8-D48 can deliver 40 Watts.

➀

These converters require a minimum 10% output loading to maintain specified regulation.
Operation under no-load conditions will not damage these devices; howe ver they ma y not
meet all listed specifications.

➁

Application-specific internal input/output filtering can recommended or perhaps added
internally upon request. Contact DATEL Applications Engineering for details.

➂

Applying a voltage to the Control pin when no input power is applied to the conve rter can
cause permanent damage to the converter. If desired, the On/Off function can be replaced
with a Sync function. See page 6 of this data sheet for more details .

Input Voltage :

"Q12/D24" Models 44 Volts
"Q48/D48" Models 88 Volts

Input Reverse-Polarity Protection Current must be <6A. Brief

duration only. Fusing recommended.

Output Overvoltage Protection

5V Outputs 6.8 Volts
12V Outputs 15 Volts

Output Current Current limited. Max. current and

short-circuit duration are model
dependent.

Storage Temperature –40 to +105°C
Lead Temperature (soldering, 10 sec.) +300°C

Floating Outputs

Since these are isolated DC/DC converters, their outputs are "floating."
Users may ground either the Common (pin 8) f or normal usage or the
positive side (+Output, pin 9) to effectively reverse the output polarity.

Filtering and Noise Reduction

All UPB 25-40 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. The caps
should be located as close to the power converters as possible. Typical
values are listed in the tables below. In many applications, using values
greater than those listed will yield better results.

To Reduce Input Ripple

"Q12, D24" Models 47µF, 50V
"Q48, D48" Models 10µF, 100V

To Reduce Output Ripple

5V 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 devices to meet your specific require­ments. Contact our Applications Engineering Group for additional details.

Input Fusing

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

V

IN Range Fuse Value

"Q12" 4A
"D24" 4A
"Q48" 3A
"D48" 2A

These are stress ratings. Exposure of devices to an y of these conditions ma y adversely
affect long-term reliability. Proper operation under conditions other than those listed in the
Performance/Functional Specifications T able is not implied.
