ULQ Models www.murata-ps.com Single Output, Low-Profile, Quarter-Brick 8-25 Amp Isolated DC-DC Converters Typical units Features ■ Standard quarter-brick package/pinout in through-hole or SMT version ■ Low cost; Low profile, 0.35" (8.9mm) ■ 24V and 48V nominal inputs ■ Output current: 8 to 25 Amps ■ Output voltages: 1.2/1.5/1.8/2/2.5/3.3/5/12V ■ Interleaved synchronous-rectifier topology · Ultra high efficiency · No output reverse conduction ■ Outstanding thermal performance ■ On/off control, trim & sense functions ■ Fully isolated, 2250Vdc (BASIC) ■ Output overvoltage protection ■ Fully I/O protected; Thermal shutdown ■ UL/EN/IEC60950 safety approvals ■ Qual/HALT/EMI tested For applications requiring improved electrical and thermal perfomance at reduced cost DATEL's new ULQ Series "Quarter-Brick" DC-DC Converters suit perfectly. They measure just 1.45 x 2.30 x 0.35 inches (36.8 x 58.4 x 8.9mm) and fit the industry-standard footprint. You can also "pick-andplace" the ULQ-SMT version optimizing your automated SMT process. 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 25A, 2.5 or 3.3V at 15 or 20A, 5V at 15A and 12V at 8-10A. They 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 noise (25-70mVp-p), and quick step response (200µsec). A state of the art, single-board, open-frame design with reduced component count, high efficiency, low-on-resistance FET's, and planar magnetics embedded in heavy-copper pc boards all contribute to impressive thermal derating. The ULQ's feature set includes high isolation (2250Vdc), input pi filters, input undervoltage shutdown, 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 output sense functions. All ULQ quarter-bricks are designed to meet the BASIC-insulation requirements of UL/EN/ IEC60950 and they will carry the CE mark. Safety certifications, EMC compliance testing and qualification testing (including HALT) are currently in progress.
