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.
