Excellent coupling coefficient (k ≥ 0.98) and 500 Vrms
isolation makes the MSD1583 series of coupled inductors
ideal for use in a variety of circuits including flyback, multi-
output buck, SEPIC and Zeta. These parts provide 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 induc-
tors, allowing selection of a part with lower DCR and higher
current handling.
