In an embodiment, a coupled-inductor structure includes first and second windings. The first winding is configured to conduct a phase current, has a first node configured for coupling to a phase node of a power supply, and has a second node configured for coupling to an output node of the power supply and to a first node of a sense impedance that is configured to generate a sense signal representative of the phase current. And the second winding is configured for magnetic coupling with the first winding, has a first node coupled to the first node of the first winding, and has a second node configured for coupling to a second node of the sense impedance. For example, the first winding may be a phase inductor of a switching power supply, and the impedance may be a capacitor that generates a sense voltage representative of the phase current.
