UQQ Series www.murata-ps.com Wide Input Range Single Output DC-DC Converters For applications requiring wide range input, improved electrical and thermal perfomance consider Murata Power Solutions new UQQ Series Quarter-Brick DC-DC Converters. They measure just 1.45 x 2.22 x 0.43 inches (36.8 x 56.4 x 10.92mm) and fit the industry-standard footprint. Typical unit FEATURES PRODUCT OVERVIEW Standard quarter-brick package/pinout in through- From an 9-36V or 18-75V input, UQQs deliver The UQQs feature set includes high isolation, hole version outputs of 3.3V, 5V,12V,15V, or 24V. They employ input pi filters, input undervoltage shutdown, output an interleaved, synchronous-rectifier topology that overvoltage protection, current limiting, short-circuit Low cost Low profile, 0.43 (10.92mm) exploits 100% of their duty cycle. They simultaneously protection and thermal shutdown. The standard 9-36V or 18-75V wide range inputs achieve ultra-high efficiency, tight line/load regulation, footprint carries on/off control (positive or negative Output current: 4 to 25 Amps low noise, and quick step response. polarity), output trim (+10/20%) and output sense functions. Output voltages: 3.3, 5, 12, 15 or 24V A state of the art, single-board, open-frame design with reduced component count, high All UQQ quarter-bricks are designed with full Interleaved synchronous-rectifier topology efficiency, low-on-resistance FETs, and planar magnetic and optical isolation up to 2250 Volts DC Ultra high efficiency magnetics embedded in heavy-copper pc boards all (basic insulation). Outstanding thermal performance contribute to impressive thermal derating. On/off control, trim & sense functions Fully isolated, up to 2250Vdc (48 Vin ) Output overvoltage protection Fully I/O protected Thermal shutdown +VOUT Certified to UL/EN/IEC60950-1, 2nd Edition safety approvals +SENSE RoHS hazardous substance compliant +VIN VOUT SENSE SWITCH VIN CONTROL ON/OFF PWM OPTO REFERENCE & TRIM CONTROL ISOLATION ERROR AMP CONTROLLER Input under/overvoltage, ISOLATION current sense, over BARRIER temperature Comparators Figure 1.
