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.

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



Input voltage range of 36-75 Vdc



3.3V, 5V, or 12Vdc ﬁxed output voltages



Isolation up to 2250 VDC (basic)



Up to 25 Watts total output power with exten-

sive self-protection shutdown features

systems, telephone equipment, vehicle and portable short-circuit protected. Additional features include



High efﬁciency synchronous rectiﬁer forward

topology up to 91%

electronics.

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

Volts DC. For powering digital systems, the outputs



Stable operation with no required external

components



Usable -40 to 85°C temperature range (with

derating)



Certiﬁed to UL 60950-1, CAN/CSA-C22.2 No.
