Shown actual size:  
4.6 x 2.2 x 0.5 in  
117 x 56 x 12,7 mm  
Typical Applications: telecommunications  
and distributed power systems  
Product Overview  
This DC-DC converter module uses  
second generation power processing, control  
and packaging technologies to provide the  
performance, flexibility and cost effectiveness  
expected of a mature Power Component.  
For example, a plated-cavity core transformer  
couples widely separated primary and  
secondary windings, resulting in low in-to-  
out parasitic capacitance and noise.  
High frequency ZCS/ZVS switching,  
advanced power semiconductor packaging  
and thermal management provide high  
power density with low temperature  
gradients. Extensive use of silicon  
integration results in 1/3 the part count  
of a first generation converter.

Thermal Resistance and Capacity  
For long pin configuration add “L” to the  
end of the part number. Slotted baseplate  
(style 1) requires no designator. For  
threaded baseplate add a “2” to the end of  
the part number. For thru-hole, add a “3”.
