Featuring a full 15 Watt or greater output in one square inch of board area, the UEI

series isolated DC/DC converter family offers efﬁ cient regulated DC power for printed

circuit board mounting.

PRODUCT OVERVIEW

Wide range 4:1 inputs on the 0.96" x 1.1" x 0.32"

converter are either 9 to 36 Volts DC (Q12 models)

or 18 to 75 Volts DC (Q48 models), ideal for battery-

powered and telecom equipment. The industry-

standard pinout ﬁ ts larger 1" x 2" converters. Fixed

output voltages from 3.3 VDC to 15 VDC are regu-

lated to within ±0.2% or less and may be trimmed

within ±10% of nominal output. Applications

include small instruments, area-limited microcon-

trollers, computer-based systems, data communi-

cations equipment, remote sensor systems, vehicle

and portable electronics.

optical isolation up to 2250 Volts DC (basic insula-

tion). For connection to digital systems, the outputs

offer fast settling to current step loads and toler-

ance of higher capacitive loads. Excellent ripple
