UEI15 Series

Isolated Wide Input Range 15-Watt DC/DC Converters

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

series isolated DC/DC converter family offers efﬁcient regulated DC power for printed

circuit board mounting.

Typical unit

FEATURES

PRODUCT OVERVIEW

Wide range 4:1 inputs on the 0.9" x 1.1" x 0.335"

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 ﬁts larger 1" x 2" converters. Fixed

output voltages from 3.3 VDC to 15 VDC are regu-

lated to within 0.2ꢀ or less and may be trimmed

within 10ꢀ 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.

The UEI 15W series includes full magnetic and

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

and noise speciﬁcations assure compatibility to

circuits using CPU’s, ASIC’s, programmable logic

and FPGA’s. For systems requiring controlled

startup/shutdown, an external switch, transis-

tor or digital logic may be used to activate the

remote On/Off control.

A wealth of self-protection features avoid both

converter and external circuit problems. These

include input undervoltage lockout and overtem-

perature shutdown. The outputs current limit using

the “hiccup” autorestart technique and the outputs

may be short-circuited indeﬁnitely. Additional

features include output overvoltage and reverse

conduction elimination.

nꢀSmall footprint DC/DC converter, ideal for

high current applications

nꢀIndustry standard 0.9" x 1.1" X 0.335"

open frame package and pinout

nꢀWide range input voltages 9-36 and

18-75 Vdc

nꢀDouble lead-free assembly and attachment

for RoHS standards

nꢀIsolation up to 2250 VDC (basic)

nꢀUp to 15 Watts or greater total output

power with overtemperature shutdown

nꢀHigh efﬁciency synchronous rectiﬁer

forward topology

The high efﬁciency offers minimal heat buildup

and “no fan” operation.

nꢀStable no-load operation with no required

external components

nꢀUsable -40 to 85°C temperature range

(with derating)

nꢀDesigned to meet UL 60950-1, CAN/CSA-

C22.2 No. 60950-1, IEC60950-1,

EN60950-1 safety approvals
