Abstract: A power controller comprises a control loop configured to control timing of pulsed signals that activate phases of a coupled inductor voltage regulator based on current demand of a load circuit and comprises a transient detection circuit configured to determine a projected current through a compensation inductor of the coupled inductor voltage regulator based on a state of the phases and operating parameters of the coupled inductor voltage regulator. The transient detection circuit is configured to detect a transient in the current demand of the load circuit based on a variability in phase-to-phase overlap of the pulsed signals. Responsive to detecting the transient, the transient detection circuit is configured to apply a correction to the control loop that alters the timing of the pulsed signals based on the projected current through the compensation inductor.

Abstract: A circuit includes a compensation inductor, a compensation resistor, and a current emulation circuit. The current emulation circuit has a time constant smaller than a time constant of the compensation inductor and the compensation resistor. The current emulation circuit includes a sense resistor having a first terminal coupled with a first terminal of the compensation inductor, and a sense capacitor having a first terminal coupled with a second terminal of the sense resistor and a second terminal coupled with ground.
