UQQ Series
Wide Input Range Single Output DC/DC Converters
For applications requiring wide range input, improved electrical
and thermal perfomance consider MPS's new UQQ Series “QuarterBrick” DC/DC Converters. They measure just 1.45 x 2.30 x 0.43 inches
(36.8 x 58.4 x 10.92mm) and fit the industry-standard footprint.

PRODUCT OVERVIEW
n compliant
RoHS
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 simultaneously achieve
ultra-high efficiency (to 91%), 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.
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 to meet the
BASIC-insulation requirements of UL/EN/IEC60950-1
and they will carry the CE mark. Safety certifications,
EMC compliance testing and qualification testing
(including HALT) are currently in progress. Contact
MPS for latest updates.
