Abstract:
1. A power controller, comprising: a first input supply node configured to receive a first input supply signal; a first output supply node configured to provide a first output supply signal; a monitor configured to monitor the first input supply signal and configured to determine if the first input supply signal is less than a first threshold, if the first input supply signal is greater than the first threshold but less than a second threshold, and if the first input supply signal is greater than the second threshold; and an adjuster configured to adjust the first output supply signal in a first manner in response to the monitor determining the first input supply signal is less than the first threshold and configured to adjust the first output supply signal in a second manner in response to the monitor determining the first input supply signal is greater than the first threshold but less than the second threshold and configured to adjust the first output supply signal in a third manner in response to the monitor determining the first input supply signal is greater than the second threshold; wherein the adjuster is configured to adjust an impedance between the first input supply node and the first output supply node in response to the monitor.
