Abstract: A method for power management for applications having duty-cycled high peak supply currents includes charging a buffer capacitor with a first current supplied by a battery, wherein the first current is limited by a current limiter. A load is supplied with a second current supplied by the buffer capacitor, wherein the second current comprises a pulsed current. The current limiter is controlled with at least one of a plurality of sensor inputs to limit a capacity degradation of the battery.
