Abstract: A voltage regulator circuit included in a computer system may include multiple phase circuits each coupled to a regulated power supply node via a corresponding inductor. The phase circuits may modify a voltage level of the regulated power supply node using respective control signals generated by a digital control circuit that processes multiple data bits. An analog-to-digital converter circuit may compare the voltage level of the regulated power supply node to multiple reference voltage levels and sample the resultant comparisons to generate the multiple data bits.

Abstract: A power converter circuit that includes a switch node coupled to a regulated power supply node via an inductor may, during a charge cycle, source current to the regulated power supply node. In response to initiating the charge cycle, a control circuit may generate a control current using a voltage level of the regulated power supply node and a reference voltage level. The control circuit may also generate compensation and correction currents that are used with a sensed inductor current to determine when to halt the charge cycle.

Abstract: A power converter is disclosed. The power converter includes a switching circuit configured to source current to a switch node that is coupled, via an inductor, to a regulated power supply node. A DC resistance sensing circuit includes a first filter and a second filters. The first filter circuit is configured to filter a voltage level of a first terminal of the inductor to generate a first filtered signal, while the second filter circuit is configured to filter a voltage level of a second terminal of the inductor to generate a second filtered signal. A control circuit is configured to adjust the operation of the switching circuit using a voltage level of the regulated power supply node, the first filtered signal, and the second filtered signal.
