Document 621-1 Coupled Inductors MSD7342 ForFlyback,SEPIC,Zeta and other Applications • Tight coupling (k ≥ 0.97) and 200 V isolation make the MSD7342 series of coupled inductors ideal for use in a variety of circuits including flyback, multi-output buck and SEPIC. • They provide high inductance, high efficiency and excellent current handling in a rugged, low cost part. • Can also be used as two single inductors connected in series or parallel, as a common mode choke or as a 1 : 1 transforme.
