| 摘要 |
A power management system for regulating supply voltage in at least two selectable power modes with low power, minimal leakage current and quicker startup times is disclosed. The power management system includes at least two regulators having regulator inputs and regulator outputs. The regulator inputs are respectively coupled to at least two voltage domains, wherein the voltage domains have different load traits and/or requirements. The power management system also includes at least one switch disposed between the regulator outputs so as to selectively interconnect the regulator outputs based on the selected power mode.
