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 2.22 x 0.43 inches (36.8 x 56.4 x 10.92mm) and fit 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 interleaved, synchronous-rectifier topology that
exploits 100% of their duty cycle. They simultane-
ously achieve ultra-high efficiency, tight line/load
regulation, low noise, and quick step response.
A state of the art, single-board, open-frame
design with reduced component count, high
efficiency, 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 filters, input undervoltage shutdown, output
overvoltage 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 with full
magnetic and optical isolation up to 2250 Volts DC
(basic insulation).
