PRODUCT OVERVIEW

Featuring a full 25 Watt output in one square inch

of board area, the UEI25 series isolated DC/DC

converter family offers efﬁ cient regulated DC power

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 ﬁ ts larger 1" x 2" converters. The ﬁ xed output

voltage is tightly regulated. Applications include

small instruments, area-limited microcontrollers,

data communications equipment, remote sensor

systems, telephone equipment, vehicle and portable

electronics.

“hiccup” autorestart technique and the outputs are

short-circuit protected. Additional features include

output overvoltage and reverse conduction elimina-
