Claim:
1. A circuit comprising: a switching regulator comprising a plurality of high side switches, a plurality of low side switches, and at least one capacitor having a first terminal coupled to a first node between the high side switches and a second terminal coupled to a second node between the low side switches, wherein the high side switches and the low side switches receive switch control signals; and a finite state machine receiving a switching signal and a duty cycle signal and generating the switch control signals, the switching signal being a digital signal indicating a polarity of an output current of the switching regulator and the duty cycle signal being a digital signal indicating whether a duty cycle of an output voltage of the switching regulator is above a threshold duty cycle, wherein the high side switches and the low side switches are turned on and off under control of the finite state machine in response to transitions in state of the switching signal and the duty cycle signal.
