1 / 16 page  UHE Series Isolated, High Efficiency, 1.6" × 2" 2-10 Amp, 12-30 Watt DC/DC Converters MDC_UHE_12-30W Series.C01 Page 1 of 16 www.murata-ps.com www.murata-ps.com/support For full details go to www.murata-ps.com/rohs FEATURES The most IOUT/POUT in this format Lower priced than bricks Small 1.6" x 2" x 0.4" plastic package with standard 2" x 2" pinout Output configurations: 1.2/1.5/1.8/2.5VOUT @ 10 Amps 3.3/5VOUT @ 25 Watts 5/12/15VOUT @ 30 Watts Five input ranges from 9-75 Volts Efficiencies as high as 91.5% Stable no-load operation Optional Sense pins for low VOUT Thermal shutdown, I/O protected 1500 Vdc I/O BASIC Insulation UL/EN60950-1 certified (2nd Edition); CE marked for Q48 models RoHS compliant The UHE 12-30W Series of high-efficiency, isolated DC/DC’s provide output power ranging from 10 Amps @ 1.2V to 2 Amps @ 15V. Offering both 2:1 and 4:1 input voltage ranges, UHE’s meet VIN requirements from 9 to 75 Volts. Taking full advantage of the synchronous- rectifier, forward topology, UHEs boast outstanding efficiency (some models exceed 91%) enabling full-power operation to ambient temperatures as high as +60°C, without air flow. Assembled using fully automated, SMT-on-pcb techniques, UHEs provide stable no-load operation, excellent line (±0.1%) and load (±0.15%) regulation, quick step response (200μsec), and low output ripple/noise (50-100mVp-p). Additionally, the UHEs unique output design eliminates one of the topology’s few shortcomings–output reverse conduction. All devices feature full I/O fault protection including: input overvoltage and undervoltage shutdown, precise output overvoltage protection (a rarity on low-voltage outputs), output current limiting, short-circuit protection, and thermal shutdown. All UHE models incorporate a VOUT Trim function and an On/Off Control pin (positive or negative logic). Low-voltage models (1.2V to 5V) offer optional sense pins facilitating either remote load regulation or current sharing for true N+1 redun- dancy. All models are certified to the BASIC insula- tion requirements of UL/EN60950-1 (2nd Edition), and 48VIN (75V max.) models carry the CE mark. Selected models are RoHS compliant (Reduction of Hazardous Substances).

Simplified Block Diagram Housed in smaller, 1.6" x 2" x 0.40" (41 x 51 x 10.2mm) packages carrying the standard 2" x 2" pinout, MPS’s new UHE Series DC/DC Converters deliver more current/power (up to 10A/30W) than currently available from either package size. |
