    • This document provides methods and apparatus configured to efficiently regulate an output voltage near a desired voltage level, for example, under varying input or load conditions. An example apparatus can include a regulator having a boost controller configured to provide voltage to an output of the regulator when at least one of the output voltage or the input voltage is below a first threshold voltage and a buck controller configured to provide voltage to the output of the regulator when at least one of the output voltage or the input voltage is above a second threshold voltage. Further, the regulator can be configured to provide the input voltage at the output of the regulator when at least one of the input voltage or the output voltage is between the first and second threshold voltages. In some examples, the first threshold is below the second threshold.

    • According to an embodiment of the present invention, a method is provided for hysteretic control of a DC-to-DC power converter system having first and second switches connected in a half-bridge arrangement at a common node and through an inductor to a regulated output terminal, wherein the regulated output terminal is connectable to an output capacitor and a load. The method includes the following: generating a feedback signal which tracks current flowing through the inductor; comparing the feedback signal against a reference voltage to general a control signal; and controlling the magnitude of an output voltage which appears at the regulated output terminal in response to the control signal, thereby providing hysteretic control of the DC-to-DC converter which is not dependent on an equivalent series resistance (ESR) of the output capacitor
