Abstract
A power converter circuit included in a computer system may include multiple devices and a switch node coupled to a regulated power supply node via an inductor. During a first time period, the power converter charges a capacitor, and the couples the capacitor to the switch node during a second time period. During a third time period the power converter couples the switch node to an input power supply node. To maintain constant charge delivered to the load during each time the switch node is coupled to the input power supply node, the duration of the third time period is adjusted based on a voltage level of the input power supply node, a voltage level of the regulated power supply node, a value of the inductor, and the durations of first and second time periods.
