Abstract
A phase-locked loop (PLL)-based power converter is disclosed. A power converter includes a switch circuit having a switch node coupled to a regulated power supply node via an inductor and configured to source a supply current to the regulated power supply node using one or more control signals. A control circuit performs a phase-frequency comparison of a reference clock signal and a switching frequency of the switch circuit and generate a control voltage using results of the phase-frequency comparison. The control circuit further generates a control current using the control voltage, a voltage of the regulated power supply node, and a duty cycle of the switch circuit, and a demand current using the voltage level of the regulated power supply node and a reference voltage. Using the demand current, the control current, and a sensed version of the supply current, the control circuit generates the one or more control signals.
