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
Wide range 4:1 inputs on the 0.9" x 1.1" x 0.335"
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.
