Isolated Wide Input Range 15-Watt DC/DC Converters

Typical unit

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.

FEATURES

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 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.
