UQQ Series

www.murata-ps.com

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.

FEATURES

PRODUCT OVERVIEW



Standard quarter-brick package/pinout in

through-hole version

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.

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.



Low cost; Low proﬁle, 0.43" (10.92mm)



9-36V or 18-75V wide range inputs



Output current: 4 to 25 Amps



Output voltages: 3.3, 5, 12, 15 or 24V

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.

All UQQ quarter-bricks are designed with full

magnetic and optical isolation up to 2250 Volts DC

(basic insulation).



Interleaved synchronous-rectiﬁer topology

 Ultra high efﬁciency



Outstanding thermal performance



On/off control, trim & sense functions



Fully isolated, up to 2250Vdc (48 VIN)



Output overvoltage protection



Fully I/O protected; Thermal shutdown
