Typical unit
UEI15 Series
Isolated Wide Input Range 15-Watt DC/DC Converters
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.
PRODUCT OVERVIEW
FEATURES
„
Small footprint DC/DC converter, ideal for
high current applications
„
Industry standard 0.96" x 1.1" X 0.32" open
frame package and pinout
„
Wide range input voltages 9-36 and 18-75 Vdc
„
Assembly and attachment for RoHS standards
„
Isolation up to 2250 VDC (basic)
„
Up to 15 Watts or greater total output power
with overtemperature shutdown
„
High efficiency synchronous rectifier forward
topology
„
Stable operation with no required external
components
„
Usable -40 to 85°C temperature range (with
derating)
„
Meets UL 60950-1, CAN/CSA-C22.2 No. 60950-
1, IEC60950-1, EN60950-1 safety approvals
„
Extensive self-protection shut down features
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 ±0.2% or less and may be trimmed
within ±10% 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.
The high efficiency offers minimal heat buildup
and “no fan” operation.
