Abstract
An apparatus includes a semiconductor switch configured to interrupt a current between a power source and a load, an inductor coupled in series with the semiconductor switch, and a capacitor coupled to a node between the inductor and the load. The apparatus further includes a current sensor configured to sense a current provided to the load and a control circuit coupled to the current sensor and configured to control the semiconductor switch responsive to the sensed current.
