摘要： The present relates to a system and method for dynamic power management of a mobile device. The mobile device has a plurality of loads and a battery charger electrically connected to a voltage rail. The method comprises monitoring the plurality of loads to determine when at least one of the loads will become active or inactive, determining a minimum required output voltage level to be provided by the voltage converter based on active loads and the at least one load that will become active or inactive and device operation; and adjusting an input voltage level via the voltage converter to provide the minimum required output voltage level on the voltage rail in advance of the at least one load becoming active or after the at least one load becomes inactive. The method further monitors the input voltage level, and determines whether the input voltage level is below a first predetermine threshold. When the input voltage level falls below the first threshold, the method reduces the output voltage level provided by the voltage converter thereby reducing a charging rate of the battery charger.
