Abstract:
A switching regulator includes a power stage for coupling to a load through an inductor. The power stage switches so that the power stage sources positive current to the load through a first transistor of the power stage during some periods and sinks negative current from the load through a second transistor of the power stage during other periods. The switching regulator further includes a protection circuit operable to force the second transistor into an off-state state responsive to the negative current flowing through the inductor exceeding a predetermined negative threshold.
