Abstract:
A method for controlling an output of a power converter includes generating a drive signal with a control circuit, entering a dormant mode of operation that includes powering down the control circuit if a flow of energy to an output of the power converter is less than a threshold value for more than a first period of time, and powering up the control circuit after it is in the dormant mode of operation for a second period of time.
