CLAIMS

WHAT IS CLAIMED IS:

1. A method for supplying power to a battery, comprising:

determining a first thermal budget for a first charging regulator;

determining a second thermal budget for a second charging regulator, the first charging regulator and the second charging regulator coupled to the battery; and

dynamically increasing a first charging regulator power output and substantially simultaneously decreasing a second charging regulator power output based at least in part on the first thermal budget and the second thermal budget.

2. The method of claim 1, in which each of the first charging regulator and the second charging regulator controls current in a first mode of operation and controls voltage in another mode of operation.

3. The method of claim 1, in which the first charging regulator and the second charging regulator are in a single integrated circuit (IC).

4. The method of claim 1, in which the first charging regulator is in a first integrated circuit (IC) and the second charging regulator is in a second IC.

5. The method of claim 1, further comprising:

determining a third thermal budget for a third charging regulator that is coupled to the battery; and

dynamically further increasing the first charging regulator power output and substantially simultaneously decreasing a third charging regulator power output based at least in part on the first thermal budget and the third thermal budget.

6. The method of claim 1, in which the first charging regulator comprises a charge pump.

7. The method of claim 1, further comprising:

sensing a temperature of a power supply coupled to inputs of the first charging regulator and the second charging regulator; and

determining whether to reduce an input power consumption of the first charging regulator and/or the second charging regulator based on the sensed temperature.

8. The method of claim 1, further comprising integrating the first charging regulator and the second charging regulator into a mobile phone, a set top box, a music player, a video player, an entertainment unit, a navigation device, a computer, a handheld personal communication systems (PCS) unit, a portable data unit, and/or a fixed location data unit.

9. A power supplying apparatus, comprising:

a first charging regulator;

at least one first heat sensor proximate the first charging regulator;

a second charging regulator, the first charging regulator and the second charging regulator coupled to a battery to supply power to the battery;

at least one second heat sensor proximate the second charging regulator; and a controller configured to dynamically increase a first charging regulator power output and substantially simultaneously decrease a second charging regulator power output based at least in part on information from the at least one first heat sensor and the at least one second heat sensor.

10. The power supplying apparatus of claim 9, in which each of the first charging regulator and the second charging regulator controls current in a first mode of operation and controls voltage in another mode of operation.

11. The power supplying apparatus of claim 9, in which the first charging regulator and the second charging regulator are in a single integrated circuit (IC).

12. The power supplying apparatus of claim 9, in which the first charging regulator is in a first integrated circuit (IC) and the second charging regulator is in a second IC.

13. The power supplying apparatus of claim 9, further comprising:

a third charging regulator coupled to the battery to supply power to the battery; and

at least one third heat sensor proximate the third charging regulator;

in which the controller is configured to further increase the first charging regulator power output and substantially simultaneously decrease a third charging regulator power output based at least in part on information for the at least one third heat sensor.

14. The power supplying apparatus of claim 9, in which the first charging regulator comprises a charge pump.

15. The power supplying apparatus of claim 9, further comprising:

a power supply coupled to inputs of the first charging regulator and the second charging regulator; and

a power supply heat sensor coupled to the power supply;

in which the controller is configured to determine whether to reduce an input power consumption of the first charging regulator and/or the second charging regulator based on measurements from the power supply heat sensor.

16. The power supplying apparatus of claim 9, integrated into a mobile phone, a set top box, a music player, a video player, an entertainment unit, a navigation device, a computer, a hand-held personal communication systems (PCS) unit, a portable data unit, and/or a fixed location data unit.

17. A power supplying apparatus, comprising:

a first charging regulator;

a first heat sensor proximate the first charging regulator;

a second charging regulator, the first charging regulator and the second charging regulator coupled to a battery to supply power to the battery;

a second heat sensor proximate the second charging regulator; and

means for dynamically increasing a first charging regulator power output and substantially simultaneously decreasing a second charging regulator power output based at least in part on information from the first heat sensor and the second heat sensor.

18. The power supplying apparatus of claim 17, in which each of the first charging regulator and the second charging regulator controls current in a first mode of operation and controls voltage in another mode of operation.

19. The power supplying apparatus of claim 17, in which the first charging regulator and the second charging regulator are in a single integrated circuit (IC).

20. The power supplying apparatus of claim 17, in which the first charging regulator is in a first integrated circuit (IC) and the second charging regulator is in a second IC.

21. The power supplying apparatus of claim 17, integrated into a mobile phone, a set top box, a music player, a video player, an entertainment unit, a navigation device, a computer, a hand-held personal communication systems (PCS) unit, a portable data unit, and/or a fixed location data unit.
