UWR Models

www.murata-ps.com

Single Output, High-Density,

6 Amp/15 Watt DC/DC Converters

Typical units

PRODUCT OVERVIEW

The new 1.2, 1.5V, 1.8V and 2.5V models in

Murata Power Solutions’ ﬂagship 7-15 Watt

A-Series can source a continuous 6 Amps. This

is the most "low-voltage" current available from

a standard 1" x 2" package, and these power

converters exemplify Murata Power Solutions’

relentless drive to bring you more power/current,

from standard packages, without compromising

reliability or resorting to thermal specmanship.

By combining a high-frequency, high-efﬁ-

ciency (to 88%), synchronous-rectiﬁer topology

with the newest components and time-tested,

fully automated, SMT-on-pcb construction, these

UWR Models are able to bring you 7-15W (@

up to 6A) in the standard 1" x 2" package from

which most competitors can only get 5-10W (@

3-4A). All UWR’s deliver their full output power

over ambient temperature ranges from –40°C

to as high as +70°C (model and input voltage

dependent) without heat sinks or supplemental

forced-air cooling. Devices derate to +100°C.

Output voltages are 1,2, 1.5, 1.8, 2, 2.5, 3.3, 5,

12 or 15 Volts. Input voltage ranges are 10-18V

(D12 models), 18-36V (D24 models) or 36-75V

(D48 models). All models feature input pi ﬁlters,

input undervoltage and overvoltage lockout, input

reverse-polarity protection, output overvoltage

protection, output current limiting, and continuous

short-circuit protection. On/off control and output-

trim functions are optional (see Optional Func-

tions). All models are designed to meet IEC950,

UL1950 and EN60950-1 safety requirements.

D48 models (36-75V inputs) are CE marked.

UWR 7-15W DC/DC’s are packaged in low-

cost, light-weight, diallyl phthalate (UL94V-0

rated) plastic packages with standoffs. EMC

compliance is achieved via a low-noise design

rather than through expensive metal shielding.
