MSD1260 Overview
Document 528-1 Coupled Inductors MSD1260 For SEPIC and other Applications .. 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.
