Quasi-continuous voltage regulator and controller

摘要

A controller for a voltage regulator includes a hysteretic circuit that generates a hysteretic voltage output as a function of a regulated voltage and that generates a hysteretic current output as a function of an inductor current. A switch control circuit provides a quasi-continuous control output as a function of the hysteretic current output from a start time when the regulated voltage rises above a higher hysteretic voltage until a stop time when the regulated voltage falls below a lower hysteretic voltage.
