UMP Models

High-Efficiency, Smaller-Package

25-40 Watt, DC/DC Converters

Features DATEL’s new UMP Models are fully potted, 25-40 Watt DC/DC converters

designed to meet UL1950 and EN60950 safety standards. The combination of the
UMP's higher efficiencies and thermally conductive potting compound enables
these devices to achiev e higher operating temperatures without derating. The
2" x 3" UMP "footprint" conforms with the standard 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,
UMP Model DC/DC’s operate from four input voltage ranges (10-36V for "Q12"
models, 18-36V for "D24" models, 18-75V for "Q48" models, and 36-75V for "D48"
models). Available output voltages are 5, 12 and 15 Volts.

For reliability and affordability, DATEL exploits contemporary, high-speed,
automatic assembly to construct the UMP’s traditional, field-proven, SMT-on-pcb
designs. Devices employ corrosion-resistant metal cases with plastic headers. Heat
generating transformer cores and power semiconductors are mounted directly to
the cases, which have threaded inserts for add-on heat sinks or pcb mounting.
Devices are specified for –40 to +100°C operation and der ating information is
provided for operation with/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. UL,
CSA, EN and IEC compliance testing is currently in progress (75V-input devices will
be CE marked) as are full EMI/EMC characterizations. Contact DATEL for the latest
available inf ormation.

UMP Model DC/DC Converters are classified, by output power, into 25, 30,
35 and 40 Watt devices. For the single-output devices listed above, the
maximum available output power is the product of the nominal output voltage
and the maximum allowable output current indicated within the part number
(see Part Number Structure). A UMP-5/6-Q48, for example, can source
6 Amps from its 5V output (over its entire 18-75V input v oltage range)
delivering an output power of 30 Watts. A UMP-5/8-D48 can deliver
40 Watts.

TECHNICAL NOTES

Floating Outputs

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

Filtering and Noise Reduction

All UMP 25-40 W att 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 UMP
DC/DC Converters, you should use slow-blow type fuses with values no
greater than the following:
