PRODUCT OVERVIEW
For eficient, 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 airlow) at full-rated power. The
optional mounting baseplate extends this to all
practical temperature ranges at full power.
UVQ’s achieve these impressive speciications
while delivering excellent electrical performance.
Overall noise is 35mVp-p (3.3V models) with fast
step response (down to 50µsec). These converters
offer high stability even with no load and tight out-
put regulation. The unit is fully protected against
input over and undervoltage, output overcur-
rent and short circuit. An on-board temperature
sensor shuts down the converter if thermal limits
are reached. Protection uses the “hiccup” (auto
restart) method.
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, UVQ’s
include a Sense input to dynamically correct for
ohmic losses. A trim input may be connected to a
user’s adjustment potentiometer or trim resistors
for output voltage calibration closer than the
standard accuracy.
UVQ’s include industry-standard safety certi-
ications and BASIC I/O insulation provides 2250
Volt input/output isolation. Radiation emission
testing is performed to widely-accepted EMC
standards. Contact MPS for details on HALT quali-
ication testing. The UVQ’s may be considered as
higher performance replacements for some MPS
USQ models.

These are partial model numbers. Please refer to the full model number struc-

Output capacitors are 1uF ceramic || 10 uF electrolytic. Input cap is 22 uF, low
ESR, except UVQ-24/4.5 is 33uF and UVQ-48/2.5 uses no input cap. I/O caps are
necessary for our test equipment and may not be needed for your application.

UVQ Pin 9 Baseplate Connection
The UVQ series may include an optional installed baseplate for extended
thermal management. Various UVQ models (see list below) are also available
with an additional pin 9 on special order which connects to the baseplate but is
electrically isolated from the rest of the converter. Please refer to the mechani-
cal drawings.
Models available with Pin 9:
UVQ-12/10-D48
UVQ-1.5/40-D24
Models which are NOT available with Pin 9:
UVQ-5/20-D24 and –D48
Pin 9 offers a positive method of controlling the electrical potential of the
baseplate, independent of the converter. Some baseplate models cannot
include pin 9 and in such cases, the baseplate is grounded by the mounting
bolts. Or consider adding an external lugged washer with a grounding terminal.
UVQ-3.3/30-D24
UVQ-3.3/35-D48
UVQ-2.5/35-D24
UVQ-2.5/40-D48
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.
Other models which are not listed will be reviewed for future pin 9 accomo-
dation.
