UQQ Series
Wide Input Range Single Output DC/DC Converters
For applications requiring wide range input, improved electrical and
thermal perfomance consider Murata Power Solutions’ new UQQ
Series “Quarter-Brick” DC/DC Converters. They measure just 1.45
x 2.30 x 0.43 inches (36.8 x 58.4 x 10.92mm) and it the industry-
standard footprint.

PRODUCT OVERVIEW
From an 9-36V or 18-75V input, UQQ’s deliver outputs
of 3.3V, 5V,12V,15V, or 24V. They employ an inter-
leaved, synchronous-rectiier topology that exploits
100% of their duty cycle. They simultaneously achieve
ultra-high eficiency (to 91%), tight line/load regula-
tion, low noise, and quick step response.
A state of the art, single-board, open-frame
design with reduced component count, high eficiency,
low-on-resistance FET’s, and planar magnetics
embedded in heavy-copper pc boards all contribute to
impressive thermal derating.
The UQQ’s feature set includes high isolation, input
pi ilters, input undervoltage shutdown, output overvolt-
age protection, current limiting, short-circuit protection
and thermal shutdown. The standard footprint carries
on/off control (positive or negative polarity), output trim
(+10/–20%) and output sense functions.
All UQQ quarter-bricks are designed to meet the
BASIC-insulation requirements of UL/EN/IEC60950-1
and they will carry the CE mark. Safety certiications,
EMC compliance testing and qualiication testing
(including HALT) are currently in progress. Contact
MPS for latest updates.


Typical at TA = +25°C under nominal line voltage and full-load conditions. All models are
specified with an external 1μF multi-layer ceramic and 10μF capacitors across their output pins
and 100μF external input capacitor.

Ripple/Noise (R/N) measured over a 20MHz bandwidth.

Devices have no minimum-load requirements and will regulate under no-load conditions.
Regulation specifications describe the output voltage deviation as the line voltage or load is
varied from its nominal/midpoint value to either extreme. (Load step = 50%.)

Nominal line voltage, no load/full load condition.

Note: Some model number combi-

Contact Murata Power Solutions.
Some model options may require minimum order quantities.
Pin 9 Baseplate Connection
The UQQ series may include an optional installed baseplate for extended
thermal management. This baseplate is electrically isolated from the rest of the
converter. Various UQQ models are also available with an additional pin 9 on
special quantity order which electrically connects to the baseplate. Pin 9 is also
isolated from the rest of the converter. Please refer to the mechanical drawings.
Pin 9 offers a positive method of controlling the electrical potential of the base-
plate, independent of the converter. If you do not include pin 9, the baseplate
may also be grounded by the mounting bolts.
The baseplate may be ordered by adding a “B” to the model number tree
and pin 9 will be pre-installed by adding a “9”. The two options are separate.
Please refer to the Ordering Guide.
Do not order pin 9 without the baseplate.
Note that “pin 9” converters may be on limited forecast, requiring minimum
order quantities and scheduled deliveries.
Please see page 9 for heatsink information.
