Abstract
Systems and methods provide for a power management unit and its operation. The power management unit includes: a step-down power converter configured to receive a first voltage and output a second voltage, wherein the second voltage is less than the first voltage and at least one step-up power converter configured to receive the second voltage and output a third voltage, wherein the third voltage is greater than the second voltage. It also includes an inductive element connected to the step-down power converter and the at least one step-up power converter and configured to store energy and selectively release the stored energy, wherein the inductive element is time shared by both the step-down power converter and the at least one step-up power converter; and a finite state machine configured to control the time sharing of the inductive element.
