57,9 x 36,8 x 12,7 mm  
Typical Applications: telecommunications  
and distributed power systems  
Product Overview  
This DC-DC converter module uses  
2nd 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 1st Generation converter.
