Abstract

In accordance with an embodiment, a method includes driving a predetermined load using a driver circuit according to a drive pattern; supplying power to the driver circuit using a switched-mode power supply (SMPS) configured to be coupled to at least one external component; and verifying functionality of the SMPS while driving the predetermined load. Verifying the functionality includes monitoring at least one operating parameter of the SMPS, where the at least one operating parameter of the SMPS is dependent on the drive pattern and the at least one external component, comparing the at least one operating parameter to at least one expected operating parameter to form a first comparison result, and indicating an error condition based on the first comparison result.
