Abstract
A power converter circuit that includes a switch node coupled to a regulated power supply node via an inductor may, during a charge cycle, source current to the regulated power supply node. In response to initiating the charge cycle, a control circuit may generate a control current using a voltage level of the regulated power supply node and a reference voltage level. The control circuit may also halt the charge cycle using results from comparisons of the compensated and uncompensated versions of the inductor current to the control current.
