摘要： 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.

摘要： A voltage regulator circuit using precharge voltage rails is generally disclosed. For example, the voltage regulator circuit may include a first voltage regulator having a voltage output, an output capacitor coupled to the voltage output, and one or more precharge voltage circuits configured to selectively couple to the voltage output, each of the one or more precharge voltage circuits comprising a capacitor coupled between an output of a precharge voltage regulator and a reference potential.
