Abstract

A current driver is coupled to an inductor; a digital control for regulation of the current driver turns the current driver on or off coupled to the current driver; a comparator output coupled to the input of the digital control for regulation of the driver with inputs to compare a voltage of the inductor to a target voltage, a digital control for selection of one of a set of peaks and valleys of allowable current levels of the current driver, the digital control for selection of one of a set of peaks and valleys coupled to the output of the comparator and an input of the current driver, the digital control for the peak/valley current to monitor the duration of each high and low output state of the comparator output to determine the selection of one of the set of peak and valley of allowable current levels for the current driver.
