Patent ID: 8217626

Claim:
A method for dynamic power management of a mobile device, the mobile device comprising a plurality of loads and a battery charger electrically connected to a variable voltage rail of the mobile device, the method comprising: 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 a single voltage converter based on voltage level requirements of all active loads and the at least one load that will become active or inactive; adjusting an input voltage level via the single voltage converter to provide the minimum required output voltage level on the variable voltage rail in advance of the at least one load becoming active or after the at least one load becomes inactive; monitoring the input voltage level; determining whether the input voltage level is below a first predetermined threshold; and when the input voltage level is below the first predetermined threshold, reducing the output voltage level provided by the voltage converter thereby reducing a charging rate of the battery charger.
