Housed in standard 2" x 2" metal packages (which have traditionally carried 15-20 Watt devices), these power converters supply up to 9 Amps @ 3.3V or 8 Amps at 5V. They exemplify Murata Power Solutions' relentless drive to bring designers more power/current, in standard packages/pinouts, without compromising reliability or resorting to thermal specmanship. Input voltage ranges are 10-18V (“D12” models), 18-36V (“D24” models) or 36-75V (“D48”) models. Employing an advanced, fully synchronous, high-frequency (300-360kHz) forward topology, UWR 26-40W singles attain 88-90% efficiencies enabling full-power operation to ambient temperatures as high as +55°C without supplemental air flow. Assembled using fully automated, SMT-on-pcb techniques, these DC/DC’s additionally provide low noise (75mVp-p), high accuracy (±1%), tight line/load regulation (±0.5%), quick step response (200µsec), and stable no-load operation. All models feature input pi filters, input undervoltage and overvoltage shutdown, output overvoltage protection, current limiting, short-circuit protection, and thermal shutdown. Each model has a VOUT trim pin as well as an on/off control function that may be ordered with either positive or negative logic. These devices are fully isolated (1500Vdc) and satisfy UL/ EN/IEC60950-1 safety requirements. “D48” models (36-75V inputs) are CE marked. FIGURE 1.

All models are specified with an external 0.47µF multi-layer ceramic capacitor installed across their output pins. Using a 10µF multi-layer ceramic capacitor instead (e.g. TDK part no. C3225X5R1C106M) will further reduce the R/N to 35mVp-p typical and 75mVp-p maximum. ➂ Load regulation is specified over 0-100% load conditions. All models are stable and regulate within spec under noload conditions, with perhaps a slight increase in output ripple/noise. ➃ Nominal line voltage, no-load/full-load conditions. ➄ Please refer to the part number structure when ordering.

See Technical Notes. Use only as much output filtering as needed and no more. Larger caps (especially low-ESR ceramic types) may slow transient response or degrade dynamic performance. ➄ The On/Off Control is designed to be driven with open-collector logic or the application of appropriate voltage levels.
