UEI30 Series
30W Isolated Wide-Range DC-DC Converters
Featuring a full 30 Watt output in 1.8 square inches of board area, the UEI
series isolated DC/DC converter family offers efficient regulated DC
power for printed circuit board mounting.

? RoHS-6 hazardous substance compliant
Wide range 4:1 inputs on the 0.92" x 1.92" x 0.35"
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. Fixed
output voltages from 3.3 VDC to 15 VDC are tightly
regulated and may be trimmed within ±10%
of nominal output. Applications include small
instruments, computer-based systems, data com-
munications equipment, remote sensor systems,
vehicle and portable electronics.
The UEI 30W Series includes full magnetic
and optical isolation up to 2250 Volts DC (basic
insulation), Q48 models. For connection to digital
systems, the outputs offer fast settling to current
step loads and tolerance of higher capacitive
loads. Excellent ripple and noise speci?cations
assure compatibility to circuits using CPU’s, ASIC’s,
SIMPLIFIED SCHEMATIC
programmable logic and FPGA’s. No minimum
load is required. For systems requiring controlled
startup/shutdown, an external switch, transistor
or digital logic may be used to activate the remote
On/Off control. Remote Sense inputs compensate
for resistive line drops at high currents.
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 inde?nitely. Additional
features include output overvoltage and reverse
conduction elimination.
The synchronous recti?er forward topology
offers high ef?ciency for minimal heat buildup
and “no fan” operation.
