Wide Input, Isolated
Eighth-Brick DC/DC Converters
T
The UWE Series "Eighth-Brick" DC/DC Converters are high-current isolated
power modules designed for use in high-density system boards.
Typical unit
PRODUCT OVERVIEW
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,
CPU cards and instrument subsystems. The extend-
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.
The synchronous rectifier design uses the
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,
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
for line drop errors at high output currents. Outputs
are trimmable within ±10% of nominal voltage. The
UWE series are functionally complete.
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.
