Abstract
A boost power converter system according to one embodiment includes an input voltage high-side node; an inductor coupled to the input voltage high-side node at a first terminal of the inductor; a power switch coupled to the inductor at a second terminal of the inductor; a drive circuit configured to control the power switch such that the boost power converter system operates in a discontinuous conduction mode when a load current drops below a critical conduction threshold; and a damping switch configured to enable current flow from the power switch at the second terminal of the inductor to the input voltage high-side node, wherein the damping switch is closed when the power switch is open and the damping switch is opened when the power switch is closed.
