Claim 5:
6. The circuit of claim 4, wherein
the state machine configured to transition from the tristate state to a recirculation state, in which the high-side switch is off and the low-side switch is on, responsive to the switch comparator output being representative of a negative voltage at the switch output terminal, and
the state machine configured to transition from the recirculation state to the HSON state responsive to the signal at the supply comparator output being representative of when a voltage at the supply input is less than the reference supply voltage at the supply reference input and when the signals at the current comparator output and the feedback comparator output are representative of both the current input and the feedback input being less than reference voltages at the respective current reference and feedback reference inputs.
