Abstract: A method and system for managing electrical current within a portable computing device (“PCD”) includes assigning a priority to two or more communications supported by the PCD. A present level of a power supply for the PCD may be monitored by a communications power (“CP”) manager module. Next, the CP manager module may determine if the two or more communications may be transmitted at the present level of the power supply. If the two or more communications cannot be transmitted at the present level of the power supply, then the CP manager module may determine if a timing of at least one of the communications may be adjusted. The CP manager module may also determine a theoretical power level adjustment for at least one of the communications. The two or more communications may be transmitted with any calculated timing off sets and power level adjustments.

Abstract: Certain aspects of the present disclosure provide a power supply system. The power supply system generally includes a first voltage regulator and a second voltage regulator, outputs of the first voltage regulator and the second voltage regulator being coupled to an output of the power supply system. The power supply system may also include a current balancer circuit configured to adjust an output current of the first voltage regulator based on determined headrooms of the first voltage regulator and the second voltage regulator.
