PRODUCT OVERVIEW
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 communications equipment, remote sensor
systems, vehicle and portable electronics.
The UEI 30W Series includes full magnetic and
optical isolation up to 2250 Volts DC (basic insu-
lation). For connection to digital systems, the out-
puts 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
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.
A wealth of self-protection features avoid
both converter and external circuit problems.
These include input undervoltage lockout 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. The open frame design
is also available under special quantity order
with an encapsulation shell and thermally-
conductive potting compound. This option offers
additional cooling in low-airflow, high tempera-
ture applications.

Soldering Guidelines
Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type. Exceeding these specifica-
tions may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your production
environment may differ; therefore please thoroughly review these guidelines with your process engineers.
