ABSTRACT:
A dynamically configurable switched capacitor power supply and a method for operation thereof. The power supply includes a first dynamically adjustable switched capacitor network having a first input, a first output and including a first plurality of n many switched capacitors. The first input is adapted to be coupled to a power source. The first dynamically adjustable switched capacitor network provides a step-up or step-down power supply regulation function in response to first control signals. The power supply includes a control network having an error detector coupled to the first output, an oscillator for providing a clocking signal, an analog to digital conversion circuit for providing a digital representation of a voltage of the power source and control logic for providing the first control signals in response to the clocking signal and in response to signals from the error detector.
