Abstract: Methods and apparatus for providing a time-interleaved current-feedback droop function for multiphase buck converters. An example method includes outputting a first control signal to enable a first set of switches corresponding to a first voltage of a first phase from a multiphase converter, the first phase included in a plurality of phases; enabling a first current associated with the first phase to be measured by a sample and hold circuit associated with the first phase; sampling the first current; holding the first current, the first current based on a load current for the first phase of the multiphase converter; and outputting a droop voltage based on a plurality of currents corresponding to the plurality of phases of the multiphase converter, the plurality of currents including the load current for the first phase.

Abstract: This invention is an SOC with an integrated single rail power supply that interfaces with the host controller and dynamically changes the host interface supply to 3.3 volts or 1.8 volts based on the sensed card speed grade. The SOC initially selects 3.3 volts to supply to the memory card. The SOC communicates with memory card vis input/output circuits to determine a memory type. The controller selects a 3.3 volt or 1.8 volt supply for the memory card based upon the determination. The SOC powers the input/output circuits at the same supply voltage as the memory card. This invention employes 1.8 volt transistors in the input/output circuits using a bias voltage to protect these transistor from the full 3.3 volt power when the memory card is powered to 3.3 volts.
