  • Publication number: 20120324246
    Abstract: Systems and methods may be implemented in a power device subsystem topology to provide an arbitration and communication scheme between a single consolidated non-volatile random access (NVRAM) memory device and multiple discrete digital power controller devices in a manner that provides data protection and the ability to update the full NVRAM content when needed.

  • Publication number: 20110248689
    Abstract: In an information handling system, a multi-phase electrical converter includes an electrical input, an electrical output, a plurality of converter phases coupled with the electrical input and the electrical output, and a controller to ramp operation of one or more of the converter phases as a load demand adjusts. In an embodiment the converter may be a multi-phase buck converter having a high side switch, a low side switch, and an inductor. In an embodiment, the controller may ramp operation of the converter phases by adjusting a duty cycle of the high side switch. In an embodiment, the controller may adjust a phase angle of one or more of the converter phases, wherein the adjustment may be relative to the ramping operation of the one or more of the converter phases.

  • Patent number: 7952418
    Abstract: An enhanced transistor gate drive is disclosed in which a pair of Kelvin sense leads measure the voltage potential across at the gate and source of the transistor. The difference in the voltage potential of the Kelvin sense lead from the gate and the Kelvin sense lead of the source is provided to a voltage controlled current source, which compares the output of the voltage differentiator to an oscillating voltage input. Changes to the voltage difference between the Kelvin sense connectors will result in more or less voltage being applied at the gate of the transistor, thereby parasitic inductance in the transistor from causing the device to switch on and off.

  • Publication number: 20110040987
    Abstract: A time averaged dynamic phase shedding system includes a system to generate a first phase electrical pulse using a phase 1 pulse generator and generate a second phase electrical pulse using a phase 2 pulse generator. The electrical current of the first phase electrical pulse and the electrical current of the second phase electrical pulse are sensed. The electrical pulses are combined into an output signal where a voltage level of the output signal is sensed. The time averaged dynamic phase shedding system turns off the phase 2 pulse generator in response to an average output current being below a current threshold and turns on the phase 2 pulse generator in response to the output signal having a change in output voltage with respect to the change in time (dv/dt) outside of a dv/dt threshold.

  • Publication number: 20090271649
    Abstract: A voltage regulator phase shedding system includes one or more subsystems to inventory memory power requirements of an IHS component, calculate a calculated memory power consumption, compare the calculated memory power consumption to a predetermined table of values to determine which phases of the voltage regulator to turn on, apply system power, assert desired phases of the voltage regulator after power is applied to the voltage regulator, and enable the voltage regulator to operate the desired phases of the voltage regulator.
