SIMPLIFIED SCHEMATIC

Featuring a full 30 Watt output in 1.8 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 0.92" x 1.92" x 0.35"

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 tightly regulated 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.

optical isolation up to 2250 Volts DC (basic insu-

lation). For connection to digital systems, the out-

puts 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

logic and FPGA’s. No minimum load is required.

down, an external switch, transistor or digital
