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.

Abstract: A configurable charge converter may include an adaptive low-dropout regulator. The adaptive low-dropout regulator may include a headroom detection circuit and a power supply controller. The headroom detection circuit may monitor a voltage drop across a field effect transistor (FET) and cause a programmable power supply to increase or decrease an output voltage accordingly. In some aspects, the configurable charge converter may include an adaptive low-dropout regulator and a buck/boost converter. The output power of the configurable charge controller may be provided by the adaptive low-dropout regulator, the buck/boost converter, or by both the adaptive low-dropout regulator and the buck/boost converter operating in combination.
