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.

Specification Notes:
(1) All models are tested and specified with external 1 μF and 10 μF parallel output capacitors and a
22 μF external input capacitor. All capacitors are low ESR types. These capacitors are necessary to
accommodate our test equipment and may not be required to achieve specified performance in your
applications. All models are stable and regulate within spec under no-load conditions.
All specifications are typical unless noted. General conditions for Specifications are +25 deg.C,
Vin=nominal, Vout=nominal, full load. Adequate airflow must be supplied for extended testing under
power.
(2) Input Back Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering
is Cin=33 μF, 100V, Cbus=220 μF, 100V, Lbus=12 μH.
(3) Note that Maximum Power Derating curves indicate an average current at nominal input voltage.
At higher temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current
outputs if the total RMS current over time does not exceed the Derating curve. All Derating curves
are presented at sea level altitude. Be aware of reduced power dissipation with increasing density
altitude.
(4) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3,
ground fixed conditions, Tpcboard=+25 deg.C, full load, natural air convection.
(5) The On/Off Control is normally selected by a switch or an open collector or open drain transistor.
But it may also be driven with external logic or by applying appropriate external voltages which are
referenced to Input Common and do not exceed the On/Off voltage specifications.
(6) Output current limiting begins when the output voltage degrades approximately 2% from the
selected setting.
(7) The outputs are not intended to sink appreciable reverse current.
(8) Output noise may be further reduced by adding an external filter. Low voltage logic circuits may
have a small voltage margin between logic ZERO and logic ONE, requiring noise suppression. Use only
as much output filtering as needed to achieve your noise requirements. Excessive output capacitance
can retard transient response or possibly cause instability. Low ESR ceramic capacitors may degrade
dynamic performance. Be sure to thoroughly test your system under full load with all components
installed.
(9) All models are fully operational and meet published specifications, including “cold start” at –40°C.
At full power, the package temperature of all on-board components must not exceed +128°C.
(10) Regulation specifications describe the deviation as the line input voltage or output load current is
varied from a nominal midpoint value to either extreme.
(11) The output overvoltage protection is automatic recovery. The overvoltage may occur either from
internal failure or from an external forcing voltage as in a shared power system.
(12) Output current limit and short circuit protection is non-latching. When the overcurrent fault is
removed, the converter will immediately recover. After an output overcurrent or short circuit, “hiccup”
operation repeatedly attempts to restart the converter with a brief, full-current output. If the overcur-
rent condition still exists, the restart current will be removed and then tried again. This short current
pulse prevents overheating and damaging the converter. Once the fault is removed, the converter
immediately resumes normal operation.
(13) Do not exceed maximum power specifications when adjusting the output trim.
(14) At zero output current, the output may contain low frequency components which exceed the
ripple specification. The output may be operated indefinitely with no load.
(15) If reverse polarity is accidentally applied to the input, to ensure reverse input protection with full
output load, always connect an external input fuse in series with the +Vin input. Use approximately
twice the full input current rating with nominal input voltage.
CAUTION: This product is not internally fused. To comply with safety agency certifications and to
avoid injury to personnel or equipment, the user must connect an external fast-blow fuse to the input
terminals. See fuse information.
