The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for preventing reverse input current from flowing into a power source, the method comprising:
providing a system having a plurality of operating modes for driving a load, wherein in each operating mode the power delivered to the load is a multiple of the power output from the power source;
transitioning the system from one operating mode into another operating mode under predetermined conditions;
if the system transitions from a higher operating mode to a lower operating mode and the power delivered to the load is greater than the power output from the power source, delaying the transition of the system from the higher operating mode into the lower operating mode.
2. The method of claim 1 comprising comparing the power delivered to the load with the power output from the power source.
3. The method of claim 1 comprising monitoring the current flow from the power source.
4. The method of claim 1 wherein the operating modes of the system comprise a 1\xd7 operating mode, a 1.5\xd7 operating mode, and a 2\xd7 operating mode.
5. The method of claim 1 wherein the load comprises at least one light emitting diode (LED).
6. The method of claim 1 wherein delaying comprises placing the system into a wait state.
7. The method of claim 1 wherein the system has a charge pump for pumping up a voltage from the power source to generate the power delivered to the load.
8. The method of claim 7 wherein delaying comprises deactivating the charge pump.
9. The method of claim 7 wherein delaying comprises deactivating the charge pump until the power delivered to the load is not greater than the power from the power source.
10. In a system having a plurality of operating modes for driving a load, wherein in each operating mode the power delivered to the load is a multiple of the power output from the power source, a method for preventing reverse input current from flowing into the power source, the method comprising:
comparing the power delivered to the load with the power output from the power source when transitioning the system from a higher operating mode into a lower operating mode; and
if the comparison finds that the power delivered to the load is greater than the power delivered from the power source, delaying the transition of the system from the higher operating mode into the lower operating mode.
11. The method of claim 10 wherein the operating modes of the system comprise a 1\xd7 operating mode, a 1.5\xd7 operating mode, and a 2\xd7 operating mode.
12. The method of claim 10 wherein the load comprises at least one light emitting diode (LED).
13. The method of claim 10 wherein delaying comprises placing the system into a wait state.
14. The method of claim 10 wherein the system has a charge pump for pumping up a voltage from the power source to generate the power delivered to the load.
15. The method of claim 14 wherein delaying comprises deactivating the charge pump.
16. The method of claim 14 wherein delaying comprises deactivating the charge pump until the power delivered to the load is not greater than the power delivered to the power source.
