ULQ Models www.murata-ps.com Single Output, Low-Profile, Quarter-Brick 8-25 Amp Isolated DC-DC Converters To Be Discontinued* Typical units Features For applications requiring improved electrical and thermal perfomance at reduced cost DATEL s new ULQ SeriesQuarter-Bric DC-DC Converters suit perfectly. They measure just 1.45 x 2.30 x Standard quarter-brick package/pinout 0.35 inches (36.8 x 58.4 x 8.9mm) and fit the industry-standard footprint. You can alsopick-and- in through-hole or SMT version plac the ULQ-SMT version optimizing your automated SMT process. Low cost Low profile, 0.35 (8.9mm) From an 18-36V or 36-75V input, ULQ s deliver outputs of 1.2, 1.5, 1.8, or 2V fully rated at 15 or 24V and 48V nominal inputs 25A, 2.5 or 3.3V at 15 or 20A, 5V at 15A and 12V at 8-10A. They Output current: 8 to 25 Amps employ an interleaved, synchronous-rectifier topology that exploits 100% of their duty cycle. They simultaneously achieve ultra-high efficiency (to 91%), tight line/load regulation (0.125/0.25%), low Output voltages: 1.2/1.5/1.8/2/2.5/3.3/5/12V noise (25-70mVp-p), and quick step response (200sec). Interleaved synchronous-rectifier topology A state of the art, single-board, open-frame design with reduced component count, high Ultra high efficiency efficiency, low-on-resistance FET s, and planar magnetics embedded in heavy-copper pc boards all No output reverse conduction contribute to impressive thermal derating. Outstanding thermal performance The ULQ s feature set includes high isolation (2250Vdc), input pi filters, input undervoltage shut - On/off control, trim & sense functions down, output overvoltage protection, current limiting, short-circuit protection and thermal shutdown. The standard footprint carries on/off control (positive or negative logic), output trim (+10/20%) and Fully isolated, 2250Vdc (BASIC) output sense functions. Output overvoltage protection All ULQ quarter-bricks are designed to meet the BASIC-insulation requirements of UL/EN/ Fully I/O protected Thermal shutdown IEC60950 and they will carry the CE mark.
