Abstract: A method may include receiving power from a power adapter having a power adapter current limit, providing power from the power adapter to a load having a load current at a first load current level that is less than or equal to the power adapter current limit; generating a first periodic current through an inductor in a forward direction; detecting the load having the load current at a second load current level that may be greater than the adapter power current limit; decreasing the forward current level of the first periodic current; and generating a second periodic current through the inductor in a reverse direction to provide power from the battery module to the load. The second periodic current may be initiated in the reverse direction when the first periodic current in the forward direction reaches the zero current level.
