FEATURES

PRODUCT OVERVIEW

ꢀ

Featuring a full 25 Watt output in one square inch

of board area, the UEI25 series isolated DC/DC

offer fast settling to step transients and will accept

higher capacitive loads. Excellent ripple and noise

Cost effective small footprint DC/DC converter,

ideal for high current applications

converter family offers efﬁcient regulated DC power speciﬁcations assure compatibility to noise-sus-

ꢀ

Industry standard 0.96" x 1.1" x 0.32" open

frame package and pinout

for printed circuit board mounting. The 0.96" x 1.1"

x 0.32" (24.4 x 27.9 x 8.1 mm) converter accepts a

2:1 input voltage range of 36 to 75 Volts DC, ideal

for telecom equipment. The industry-standard pin-

out ﬁts larger 1" x 2" converters. The ﬁxed output

voltage is tightly regulated. Applications include

small instruments, area-limited microcontrollers,

data communications equipment, remote sensor

ceptible circuits. For systems requiring controlled

startup/shutdown, an external remote On/Off control

may use a switch, transistor or digital logic.

ꢀ

Input voltage range of 36-75 Vdc

A wealth of self-protection features avoid both

converter and external circuit faults. These include

input undervoltage lockout and overtemperature

shutdown. The outputs current limit using the

“hiccup” autorestart technique and the outputs are

output overvoltage and reverse conduction elimina-

tion. The high efﬁciency offers minimal heat buildup

and “no fan” operation.

The UEI25 series includes full magnetic and

optical isolation with Basic protection up to 2250
