Abstract: According to another embodiment, a system includes a driver circuit that drives a first output and a second output; a coil coupled between the first output and the second output such that the driver circuit drives current through the coil in response to control signals; and a programmable slew circuit coupled to the driver circuit. In some embodiments, a switch is coupled between the first output and the coil. In some embodiments an over-voltage protection circuit is coupled to protect the driver circuit.

Abstract: A charging system that includes a switching control circuit coupled to four series-coupled MOSFET transistors; a flying capacitor coupled across two of the four series-coupled MOSFET transistors; and node between the two of the four series coupled transistors that couples to an output inductor to form a buck regulator is presented. Embodiments of the charging system can have increased efficiency, can reduce the size and inductance of the output inductor, and can be produced with a low voltage process.
