Abstract
Various embodiments provide a magnetic sensing scheme for a voltage regulator circuit. The voltage regulator circuit may include a first inductor (also referred to as an output inductor) coupled between a drive circuit and an output node. The voltage regulator circuit may further include a second inductor (also referred to as a sense inductor) having a first terminal coupled to the first inductor at a tap point between terminals of the first inductor. The second inductor may provide a sense voltage at a second terminal of the second inductor. A control circuit may control a state of the voltage regulator circuit based on the sense voltage to provide a regulated output voltage at the output node. Other embodiments may be described and claimed.
