Abstract
A voltage regulator circuit using predictively precharged voltage rails is generally disclosed. For example, the voltage regulator circuit may include a main switching regulator configured to provide a target voltage, the main switching regulator having a first voltage node, a precharge switching regulator configured to provide a precharge voltage, the precharge switching regulator having a second voltage node, the precharge voltage based on a difference between the target voltage and a next target voltage to be provided by the main switching regulator, and a precharge switch circuit configured to selectively couple the second voltage node to an output voltage node based upon a transition from the target voltage to the next target voltage.
