Wide Input, Isolated

Eighth-Brick DC/DC Converters

The UWE Series "Eighth-Brick" DC/DC Converters are high-current isolated

power modules designed for use in high-density system boards.

PRODUCT OVERVIEW

Typical unit

With dimensions of only 0.9 by 2.3 by 0.38

inches, the UWE series open frame DC/DC convert-

ers deliver up to 75 Watts in an industry-standard

“eighth-brick” through-hole package. This format

can plug directly into quarter-brick pinouts. Several

standard ﬁxed-output voltages from 3.3 Vdc to 24

Vdc assure compatibility in embedded equipment,

tight line/load regulation, stable no-load operation

and fast load step response. All units are precision

assembled in a highly automated facility with ISO-

traceable manufacturing quality standards.

Isolation of 1500 Volts assures safety and fully

differential (ﬂoating) operation for greatest applica-

tion ﬂexibility. On-board Sense inputs compensate

CPU cards and instrument subsystems. The extend- for line drop errors at high output currents. Outputs

ꢀ

ed 4-to-1 input power range (9-36V) is ideal for

battery-powered, telecom or portable applications.

Very high efﬁciency means no fans or temperature

deratings in many applications. An optional thermal

mounting baseplate extends operation into most

conceivable environments.

are trimmable within 10ꢀ of nominal voltage. The

UWE series are functionally complete.

Fixed output from 3.3 to 24 Volts DC up to 75

Watts

A wealth of protection features prevents damage

to both the converter and outside circuits. Inputs

are protected from undervoltage and outputs fea-

ture short circuit protection, overcurrent and excess

temperature shut down. Overloads automatically

recover using the “hiccup” technique upon fault

removal. The UWE is designed to meet all standard

safety and EMI/RFI certiﬁcations. All units meet

RoHS-6 (no lead) hazardous materials compliance.

ꢀ

Synchronous rectiﬁcation yields very high

efﬁciency and low power dissipation

ꢀ

Operating temperature range from -40 to

+85˚C with derating

The synchronous rectiﬁer design uses the

ꢀ

Up to 1500 Volt DC isolation (basic insulation)

maximum available duty cycle for greatest ef-

ﬁciency and low power dissipation with no reverse

output conduction. Other features include low

on-resistance FET’s, planar magnetics and heavy-

copper PC boards. These deliver low output noise,

Extensive self-protection, overtemperature

and overload features with no output reverse
