UWR 26-40W Series

www.murata-ps.com

Single Output, High-Density, 3.3VOUT and 5 VOUT, 26-40 Watt, DC/DC Converters

NOT RECOMMENDED

FOR NEW DESIGNS

FEATURES



Standard 2" x 2" packages/pinouts

PRODUCT OVERVIEW



Output voltages/currents:

The newest products in DATEL’s flagship A-Series are the UWR, 26-40 Watt isolated

singles. 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 DATEL’s 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.

•

3.3 Volts @ 8/9 Amps

5 Volts @ 7/8 Amps

•



Choice of 3 input voltage ranges:

10-18V, 18-36V, 36-75V



Fully synchronous forward topology



Outstanding performance:

Employing an advanced, fully synchronous, high-frequency (300-360kHz) forward to-

pology, UWR 26-40W singles attain 88-90ꢀ 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 ( 1ꢀ), tight line/load regulation ( 0.5ꢀ), 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 shut-

down. 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.
