Abstract
In some examples, a device comprises a power conversion circuit that includes: an inductor having a first end coupled to an input voltage terminal; a first switch coupled to a second end of the inductor at a first node; a second switch coupled to the second end of the inductor and the first switch at the first node; a third switch coupled to the first switch and to another input voltage terminal at a second node; and a fourth switch coupled to the second switch and to the another input voltage terminal at the second node. The device also comprises a control circuit comprising a variable delay circuit coupled to the first and second switches; and a controller coupled to the variable delay circuit, to an inductor current sensor, and to an input voltage sensor, the inductor current sensor coupled to the inductor and the input voltage sensor coupled to the input voltage terminal and the another input voltage terminal.
