UVQ Series www.murata-ps.com Low Profile, Isolated Quarter Brick 2.5-40 Amp DC/DC Converters PRODUCT OVERVIEW Typical unit FEATURES Standard quarter-brick package/pinout Outputs from 1.5 to 48V up to 125W Low profile 0.42" height 24 and 48Vdc nominal inputs Fully isolated, 2250Vdc (BASIC) insulation Designed for RoHS-6 compliance Output overvoltage/short-circuit protected On/Off control, trim and sense functions High efficiency to 92% Protected against temp. and voltage limits Designed to meet UL/IEC/EN60950-1 safety approvals A convenient remote On/Off control input operates 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 certifications and BASIC I/O insulation provides 2250 Volt input/output isolation. Radiation emission 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. For efficient, fully isolated DC power in the smallest 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 +70C at 200 lfm airflow) at full-rated power. The optional mounting baseplate extends this to all practical temperature ranges at full power. UVQ's achieve these impressive specifications while delivering excellent electrical performance. Overall noise is 35mVp-p (3.3V models) with fast step response (down to 50sec). These converters offer high stability even with no load and tight output regulation. The unit is fully protected against input over and undervoltage, output overcurrent 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 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 mechanical drawings. 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. 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.
