Abstract
The invention provides a method for improving efficiency of a power converter which may include a switch coupled between a power source and a middle node, and may supply an inductor current at the middle node to result in an output voltage and a load current. The method may comprise: during an intermediate mode, controlling the inductor current to ripple with peaks at a peak current threshold and valleys which may vary as the load current varies.
