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 t the industry- standard footprint. Typical unit FEATURES PRODUCT OVERVIEW Standard quarter-brick package/pinout in From an 9-36V or 18-75V input, UQQs deliver The UQQs feature set includes high isolation, through-hole version outputs of 3.3V, 5V,12V,15V, or 24V. They employ input pi lters, input undervoltage shutdown, output an interleaved, synchronous-recti er topology that overvoltage protection, current limiting, short-circuit Low cost Low pro le, 0.43 (10.92mm) exploits 100% of their duty cycle. They simultane- protection and thermal shutdown. The standard 9-36V or 18-75V wide range inputs ously achieve ultra-high ef ciency, tight line/load footprint carries on/off control (positive or negative Output current: 4 to 25 Amps regulation, 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-recti er topology ef ciency, low-on-resistance FETs, and planar magnetic and optical isolation up to 2250 Volts DC Ultra high ef ciency magnetics embedded in heavy-copper pc boards (basic insulation). Outstanding thermal performance all contribute to impressive thermal derating.
