Featuring a full 50-60 Watt output in 2.9 square inches 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 1.50" x 1.90" x

0.38" 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

regulated to within ±0.05% 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.

and optical isolation up to 2250 Volts DC (basic

insulation). For connection to digital systems, the

outputs offer fast settling to current step loads

and tolerance of higher capacitive loads. Excellent

ripple and noise speciﬁ cations assure compatibil-

ity to circuits using CPU’s, ASIC’s, programmable
