An electronic device may include electrical components. Each component may be powered at a different respective voltage. Voltage converter circuitry may convert a power supply input voltage into a suitable voltage for powering a corresponding component. The converter may include permanent magnets that include hard ferromagnetic materials. An inductor may be formed adjacent to the permanent magnets and within the magnetic field. The magnetic field may contribute to the inductance of the inductor. The inductor may be coupled between power switching circuitry and an output path. The power switching circuitry may receive the input voltage and may apply a duty cycle to the input voltage to generate an intermediate signal. The inductor may generate an output voltage having a different magnitude than the input voltage based on the intermediate signal. The inductor may provide the output voltage to the electrical component over the output path for powering the electrical component.
