Typical unit
For efcient, 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 airow) at full-rated power. The
optional mounting baseplate extends this to all
practical temperature ranges at full power.
UVQ’s achieve these impressive specications
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.
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 resis-
tors for output voltage calibration closer than the
standard accuracy.
UVQ’s include industry-standard safety
certications and BASIC I/O insulation provides
2250 Volt input/output isolation. Radiation emis-
sion testing is performed to widely-accepted
EMC standards. The UVQ’s may be considered
as higher performance replacements for some
Murata Power Solutions USQ models.
