Abstract:
1. An apparatus comprising: an error circuit that is coupled to a feedback terminal so as to receives a feedback signal; control logic that is coupled to the error circuit; a high side driver that is coupled to the control logic and to a first output terminal so as to provide a first actuation signal; a low side driver that is coupled to the control logic and to a second output terminal so as to provide a second actuation signal; an interface circuit that is coupled to the control logic, wherein the interface circuit includes: an undervoltage comparator that receives a first reference voltage and that is coupled to the feedback terminal and the control logic; and an overvoltage comparator that receives a second reference voltage and that is coupled to the feedback terminal and the control logic, wherein the overvoltage comparator and undervoltage comparator are disabled for a predetermined period following a change between voltage identification (VID) signals.
