Abstract
In one embodiment, a method is provided for preventing reverse input current from flowing into a power source. The method includes: 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 power delivered to the load is greater than the power delivered to the power source, delaying the transition of the system from the one operating mode into the other operating mode
