Abstract
Provided is a controller circuit for a series capacitor step-down converter that drives the series capacitor step-down converter at a switching frequency fhigher than a frequency frepresented by the following Equation wherein L is a design value for an inductance value of at least two inductors constituting a coupled inductor of the series capacitor step-down converter, M is a design value for a mutual inductance of the at least two inductors, and Cis a design value of a capacitance of a series capacitor.
