PRODUCT OVERVIEW
For efficient, fully isolated DC power in the small-
est space, Murata Power Solutions' UVQ series
quarter bricks offer output voltages from 1.5
to 48 Volts with currents up to 40 Amps. UVQs
operate over a wide temperature range (up to
+70°C at 200 lfm airflow) at full-rated power. The
optional mounting baseplate extends this to all
practical temperature ranges at full power.
UVQs achieve these impressive specifications
while delivering excellent electrical performance.
Overall noise is 35mVp-p (3.3V models) with fast
step response (down to 50µsec). These convert-
ers offer high stability even with no load and
tight output regulation. The unit is fully protected
against input over and undervoltage, output over-
current and short circuit. An on-board temperature
sensor shuts down the converter if thermal limits
are reached. Protection uses the “hiccup” (auto
restart) method.
UVQ Series
Low Profile, Isolated Quarter Brick
2.5–40 Amp DC-DC Converters
A convenient remote On/Off control input oper-
ates by external digital logic, relay or transistor
input. To compensate for longer wiring and to
retain output voltage accuracy at the load, UVQs
include a Sense input to dynamically correct for
ohmic losses. A trim input may be connected to a
user’s adjustment potentiometer or trim resis-
tors for output voltage calibration closer than the
standard accuracy.
UVQs include industry-standard safety certifica-
tions and BASIC I/O insulation provides 2250 Volt
input/output isolation. Radiation emission testing
is performed to widely-accepted EMC standards.
The UVQs may be considered as higher perfor-
mance replacements for some Murata Power
Solutions USQ models.
