Abstract

A voltage regulator includes a control circuit configured to output a plurality of enable signals, and a power stage including a plurality of phase circuits. Each phase circuit of the plurality of phase circuits includes a node, an inductor coupled between the node and an output node of the voltage regulator, a plurality of p-type transistors coupled between the node and a power supply node of the voltage regulator, and a plurality of n-type transistors coupled between the node and a reference node of the voltage regulator. Each phase circuit of the plurality of phase circuits is configured to, responsive to the plurality of enable signals, selectively couple the node to the power supply node through a first subset or all of the plurality of p-type transistors, and selectively couple the node to the reference node through a second subset or all of the plurality of n-type transistors.
