Abstract
An electronic device for controlling switching timing is described. The electronic device includes load voltage measuring circuitry configured to measure a load voltage to produce a load voltage measurement. The electronic device also includes a processor coupled to the load voltage measuring circuitry. The processor is configured to determine whether a load voltage spike is indicated by the load voltage measurement. The processor is configured to control switching timing based on whether a load voltage spike is indicated.
