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  
  
Industry-standard through-hole eighth-brick  
package with 0.9" x 2.3" x 0.38" outline  
dimensions  
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 2250 Volts (Q48 models) assures  
safety and fully differential (floating) operation for  
greatest application flexibility. On-board Sense in-

CPU cards and instrument subsystems. The extend- puts compensate for line drop errors at high output  
  
Synchronous rectification yields very high  
efficiency and low power dissipation  
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.  
currents. Outputs are trimmable within 10ꢀ of  
nominal voltage. The UWE series are functionally  
complete.  
  
Operating temperature range from -40 to  
+85˚C with derating  
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 certified to standard safety  
and EMI/RFI approvals. All units meet RoHS-6  
hazardous materials compliance.  
  
Up to 2250 Volt DC isolation (Q48 models)  
  
Outstanding thermal performance and derating  
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,
