Claim 16:
17. The switched multi-cell battery system of claim 16, wherein:
the plurality of rechargeable battery cells further comprises a third rechargeable battery cell;
the plurality of power control switches includes at least four additional power control switches by which the third rechargeable battery cell is coupled to the input voltage node, the output voltage node, and the ground node; and
the power management integrated controller is further configured to:
during the first phase of the duty cycle, control the plurality of power control switches effective to (i) couple the plurality of the rechargeable battery cells in series between the input voltage node and the ground node and (ii) couple the third rechargeable battery cell between the output voltage node and the ground node; and
during the second phase of the duty cycle, control the plurality of power control switches effective to (i) couple the plurality of the rechargeable battery cells in series between the input voltage node and the ground node and (ii) couple the first or the second rechargeable battery cell between the output voltage node and the ground node.
