50-60W Isolated Wide-Range DC/DC Converters

Featuring a full 50-60 Watt output in 2.9 square inches of board area,

the UEI series isolated DC/DC converter family offers efficient

regulated DC power for printed circuit board mounting.

PRODUCT OVERVIEW

Typical unit

Wide range 4:1 inputs on the 1.50" x 1.90" x

0.38" 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

regulated to within 0.05ꢀ and may be trimmed

within 10ꢀ of nominal output. Applications

include small instruments, computer-based

systems, data communications equipment, remote

sensor systems, vehicle and portable electronics.

logic and FPGA’s. No minimum load is required.

For systems requiring controlled startup/shut-

down, 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.

FEATURES



Small footprint DC/DC converter, ideal for high

current applications



Industry standard 1.50˝x1.90˝ x0.38˝ open

frame package and pinout

A wealth of self-protection features avoid both

converter and external circuit problems. These

include input undervoltage lockout, input overvolt-

age and overtemperature 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.

The synchronous rectiﬁer forward topology offers

high efﬁciency for minimal heat buildup and “no

fan” operation.



Wide range input voltages 9-36 and 18-75Vdc



Assembly and attachment for RoHS standards



Isolation up to 2250 VDC (basic)

The UEI 50-60W Series includes full magnetic

and optical isolation up to 2250 Volts DC (basic

insulation). For connection to digital systems, the

outputs offer fast settling to current step loads

and tolerance of higher capacitive loads. Excellent

ripple and noise speciﬁcations assure compatibil-

ity to circuits using CPU’s, ASIC’s, programmable



Up to 50-60W total output power with

overtemperature shutdown



High efﬁciency synchronous rectiﬁer forward

topology



Stable no-load operation with no required

external components



–40 to +85°C temperature range with derating



Certiﬁed to UL60950-1, CSA-C22.2 No. 234,

EN60950-1, 2nd Edition safety approvals



Extensive self-protection shut down features



RoHS-6 compliant
