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.

Abstract: A methodology and apparatus are disclosed for providing standby power during standby mode by applying a low frequency sampling clock signal to first and second comparators which are connected to compare an output voltage generated at an external capacitor to, respectively, a first higher voltage threshold and a second lower voltage threshold, where the first comparator generates an enable signal in response to the output voltage reaching the first higher voltage threshold for use in activating one or more switched regulator circuits to pump up the output voltage at the external capacitor to exceed the first higher voltage threshold, and where the second comparator generates an undervoltage signal in response to the output voltage reaching the second lower voltage threshold for use in reactivating the main regulator to pump up the output voltage at the external capacitor to exceed the first higher voltage threshold.

Abstract: One example discloses, an apparatus for power management, having: a power input node configured to receive charge from a primary power source at a first power level; a power-converter, having an enabled state and a disabled state, and coupled to receive the charge from the power input node; an energy buffer, coupled to receive and store the charge from the power-converter, and configured to release the charge at a second power level; a power output node, coupled to receive the charge from the energy buffer, and configured to supply the charge at the second power level to a load; wherein the second power level is greater than the first power level; and wherein the power-converter switches between the enabled state and the disabled state based on whether the charge is supplied to the load.
