Coupled Inductors MSD1514

• Excellent coupling coefﬁcient (k ≥ 0.97)

• Ideal for use in a variety of circuits including ﬂyback, multi-

output buck, SEPIC, Zeta, and Ćuk.

• High inductance, high efﬁciency and excellent current handling.

• In SEPIC topologies, the required inductance for each winding

is half the value needed for two separate inductors, allowing

selection of a part with lower DCR and higher current handling.
