UWS Series

www.murata-ps.com

Sixteenth-brick DOSA-Compatible,

Wide Input Isolated DC-DC Converters

FEATURES



High efﬁciency synchronous ﬂyback topology



18-75 Volts DC wide input range with 3.3, 5 and

12 Volts for Output voltage

Typical units



Up to 54 Watts total output power with

overtemperature shutdown

PRODUCT OVERVIEW



Tiny 1.30" x 0.90" x 0.36" open frame package

The world of “brick” DC-DC converters has seen

a steady size reduction. The UWS series makes

another dramatic size shrink down to a “sixteenth- remote On/Off control may use a switch, transistor

brick” width (0.90 inches) while still retaining a

high power output and full 2250 Volt DC isolation.

The PC-board mount converter family accepts



Extensive self-protection shut down features

or digital logic.

Many self-protection features on the UWS series

avoid both converter and external circuit hazards.



Small footprint DC-DC converter, ideal for high

current applications

18 to 75 Volts DC inputs and delivers ﬁxed outputs These include input undervoltage lockout and



2250 Volt Basic input/output isolation (48V

models)

regulated to within 0.125ꢀ. The UWS converters

are ideal for datacom and telecom applications,

cell phone towers, data centers, server farms and

network repeaters.

UWS outputs may be trimmed while delivering

fast settling to current step loads and no adverse

effects from higher capacitive loads. Excellent ripple

and noise speciﬁcations assure compatibility to cir-

cuits using CPU’s, ASIC’s, programmable logic and

overtemperature shutdown. The output of these

DC-DC converters have current limit using the

“hiccup” autorestart technique and the outputs may

be short-circuited indeﬁnitely. Additional features

include output overvoltage and reverse conduction

elimination.

The synchronous ﬂyback topology yields high

efﬁciency for minimal heat buildup and “no fan”

operation.



Operating temperature range -40 to +85°C with

derating



Stable no-load operation with no required exter-

nal components



Certiﬁed to UL 60950-1, 2nd Edition, EN60950-1
