PRODUCT OVERVIEW

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 ﬁ ts 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 speciﬁ cations 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 indeﬁ nitely. Additional

features include output overvoltage and reverse

conduction elimination.

The high efﬁ ciency offers minimal heat buildup

and “no fan” operation.

UEI15 Series Isolated Wide Input Range 15-Watt DC/DC Converters TECHNICAL NOTES Input Fusing Certain applications and/or safety agencies may require fuses at the inputs of power conversion components. Fuses should also be used when there is the possibility of sustained input voltage reversal which is not current-limited. For greatest safety, we recommend a fast blow fuse installed in the ungrounded input supply line. The installer must observe all relevant safety standards and regulations.

Measuring Output Ripple and Noise (PARD) and a DC leakage resistance. When using the isolation feature, do not allow the isolation voltage to exceed speciﬁcations. Otherwise the converter may be damaged. Designers will normally use the negative output (-Output) as the ground return of the load circuit.

UEI15 Series Isolated Wide Input Range 15-Watt DC/DC Converters reduces the average output current, thereby preventing excessive internal temperatures. A short circuit can be tolerated indeﬁnitely. Trimming the Output Voltage The Trim input to the converter allows the user to adjust the output voltage over the rated trim range (please refer to the Speciﬁcations).

UEI15 Series Isolated Wide Input Range 15-Watt DC/DC Converters disabled when the On/Off is grounded or brought to within a low voltage (see Speciﬁcations) with respect to –VIN. Negative-logic devices are on (enabled) when the On/Off is grounded or brought to within a low voltage (see Speciﬁcations) with respect to –VIN. The device is off (disabled) when the On/Off is left open or is pulled high to +15VDC max. with respect to –VIN.
