Patent ID: 8040116

Claim:
An automatically configurable dual regulator type circuit comprising: a high-side switching device (HS-SD) coupled to a low-side switching device (LS-SD) at an output node; and 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, wherein the HS-SD and the LS-SD are both used in one regulator type configuration mode, and wherein the control logic device discharges the output user selected circuit configuration, after a predetermined delay of the voltage of the output terminal exceeding the first threshold, by turning on the LS-SD until the voltage of the output terminal falls below a second threshold.
