Abstract
A power converter circuit that includes a switch node coupled to a regulated power supply node via an inductor may, in response an assertion of a control signal, source current to the regulated power supply node. In response to initiating a charge cycle, a control circuit may assert the control signal. During an assertion of the control signal, the control circuit may adjust a slope of a transition of the control signal using a voltage level of the switch node.
