MSC1278 Applications  
The MSC1278 coupled inductors are designed with  
high leakage inductance for use in SEPIC applications.  
The loosely coupled windings (K ≈ 0.8) improve SEPIC  
efficiency by reducing circulating current and provide  
twice the ripple current reduction of separate inductors.  
These inductors offer high efficiency and excellent cur-  
rent handling in a rugged, low cost part. They are well  
suited for use as aVRM inductors in high-current DC-DC  
converters and VRM/VRD controllers.  
They can also be used as two single inductors connected  
in series or parallel.
