Abstract

A power converter circuit that includes a switch circuit, and multiple phase and amplifier circuits, may generate a voltage level on a regulated power supply node of a computer system. The amplifier circuits may generate respective demand currents using a voltage level of the regulated power supply node and a reference voltage. In response to activation of a multi-phase operating mode, the switch circuit may short the outputs of the amplifier circuits to generate a common demand current. The multiple phase circuits may sequentially source current to regulated power supply node using the common demand current.
