Abstract
A switching converter provides an output voltage, and includes a first switch, a gate driver and an over-current management block. The gate driver is operable to drive the first switch with an ON duration of a first magnitude normally to provide the output voltage. The ON duration corresponds to a first phase of each cycle of a sequence of cycles of a periodic clock signal employed in the switching converter. The over-current management block is operable to determine a potential over-current condition when the switch operates with an ON duration of a first magnitude. In response to the determination, the over-current management block is operable to cause the gate driver to increase an ON duration of the first switch to a second magnitude, and examine a magnitude of current through the first switch with ON duration of the second magnitude to determine whether actual over-current condition is present.
