1. A method of balancing current supplied by a plurality of regulators coupled to a load, comprising:
- measuring an average load current supplied by each regulator;
determining an overall average current to be shared by the plurality of regulators;
comparing each average load current with the overall average current to be shared by the plurality of regulators; and
adjusting an output current of one or more of the plurality of regulators so that the plurality of regulators supply the same current to the load.

Abstract
A method of balancing current supplied by a plurality of regulators coupled to a load includes: measuring an average load current supplied by each regulator; determining an overall average current to be shared by the plurality of regulators; comparing each average load current with the overall average current to be shared by the plurality of regulators; and adjusting an output current of one or more of the plurality of regulators so that the plurality of regulators supply the same current to the load.

9. A method of supplying current to a load, comprising:
-
supplying current to the load during a first phase via a first regulator; supplying current to the load during a second phase via a second regulator; determining a first average current provided to the load during the first phase and a second average current provided to the load during the second phase; determining an overall average current to be shared by the first and second regulators; comparing the first average current provided to the load during the first phase with the overall average current to be shared by the first and second regulators; and comparing the second average current provided to the load during the second phase with the overall average current to be shared by the first and second regulators. - View Dependent Claims (10, 11, 12)

13. A method of supplying current to a load, comprising:
-
coupling a first regulator to the load; coupling a second regulator to the load; balancing a current provided by the first regulator to the load and a current provided by the second regulator to the load based on a comparison of an overall average current value with the current provided by each regulator; coupling an input of the first regulator and an input of the second regulator to a first plate of a capacitor; coupling an output of the first regulator and an output of the second regulator to a second plate of the capacitor; and determining the overall average current value at the first plate of the capacitor. - View Dependent Claims (14, 15)
