Abstract: A controller for a switching regulator incorporates a protection circuit to limit the negative current to a negative current threshold while operating the switching regulator to sink current from the load without damage to the power switches. In some embodiments, in response to the negative current reaching the negative current threshold, the protection circuit turns off the low-side power switch and turns on the high-side power switch for a maximum time period. In the event the negative current has not recovered, the high-side power switch and the low-side power switch are both turned off while the high-side power switch conducts the negative current through the high-side power switch body diode. When the negative current recovers to a recovery level, the low-side power switch can then be turned on. The protection circuit repeats the process each time the negative current is detected to have reached the negative current threshold.
