Surface Mount Coupled Inductors Slide 7

A ZETA converter is similar to a SEPIC converter but it uses a buck controller. Using a 1:1 dual winding inductor in this circuit divides the inductor ripple current equally between the windings with one half going through each winding. The inductance (L) of the dual windings will also be divided by two.
