Abstract
Automatically configurable dual regulator type circuits and methods are provided. On embodiment of the invention includes an automatically configurable dual regulator type circuit. The circuit comprises a high-side switching device (HS-SD) coupled to a low-side switching device (LS-SD) at an output node. The circuit further comprises a control logic device that turns on the HS-SD to provide an output current to a user selected circuit configuration through the output node, turns off the HS-SD after a voltage fed back from an output terminal of the user selected circuit configuration exceeds a first threshold and sets a regulator type configuration mode based on the presence or absence of a flyback period at the output node after the HS-SD has been turned off.
