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.

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.

Basic protection up to 2250 (Q48 models) Volts DC.

For connection to digital systems, the outputs offer

fast settling to current step loads and tolerance of

higher capacitive loads. Excellent ripple and noise
