  • Publication number: 20080204098
    Abstract: Current sharing scheme based on input power and/or the power efficiency for a power stage with multiple phases and/or paralleled modules is described. According to the scheme, duty cycles of different phases/modules may be adaptively adjusted until the minimum input power and/or the maximum power efficiency is achieved. For certain input voltages, the minimum input power exists at the minimum total input current. Thus, input power and/or the input current may be used as an indicator of the maximized power efficiency of the power stage and hence be used to track the optimal current sharing ratio among the multiple phases/modules.

  • Publication number: 20080203992
    Abstract: A controller for a power stage may adaptively control power switches to improve the efficiency of power consumption by the power stage and detect continuous conduction mode (“CCM”) and discontinuous conduction mode (“DCM”) operations of the power stage without instantaneous or cycle by cycle sensing and sampling of the output inductor current. Additionally, the controller may be used to facilitate the estimation of output inductor value, the peak inductor current value, and other information on converter operations.

  • Publication number: 20060294400
    Abstract: Systems and methods of power management provide for using transient running average power limits to enhance device power consumption and platform power delivery. A transient running average power limit can be transmitted to a device based on system device load demand and/or a characteristic of a power delivery system associated with the device.
