For SEPIC and other  
Applications  
Coupled Inductors  
MSD1260  
The excellent coupling coefficient (k 0.94) makes the  
MSD1260 series of coupled inductors ideal for use in  
SEPIC applications. In SEPIC topologies, the required  
inductance for each winding in a coupled inductor is half  
the value needed for two separate inductors, allowing  
selection of a part with lower DCR and higher current  
handling.  
These parts provide high inductance, high efficiency  
and excellent current handling in a rugged, low cost  
part. They are also well suited for use as a VRM  
inductors in high-current DC-DC converters and VRM/  
VRD controllers.  
They can also be used as two single inductors con-  
nected in series or parallel, as a common mode choke  
or as a 1 : 1 transformer.
