Techniques and mechanisms for determining an operational mode of a voltage regulator. In an embodiment, an integrated circuit (IC) die is coupled to receive power from a voltage regulator (VR) via a power delivery network (PDN) which comprises circuitry in or on a substrate, such as that of a printed circuit board. The IC die receives from the substrate information indicating a characteristic of a parasitic impedance at the substrate. Based on the information, a controller unit at the IC die selects one of multiple VR modes which each correspond to a respective one of different parasitic impedance characteristics. The controller then signals the VR to provide the selected mode. In an embodiment one of the VR modes corresponds to a relatively high impedance, and also corresponds to a relatively stable sensitivity function in a frequency range above a control bandwidth.

Described is an apparatus which comprises: a first voltage regulator (VR) coupled to first one or more inductors, the first VR is to provide power to a first power domain; and a second VR coupled to second one or more inductors at least one of which is inductively coupled to at least one of the first one or more inductors, the second VR is to provide power to a second power domain separate from the first power domain, wherein there is a non-zero phase angle offset between switching transistors of the first VR relative to the second VR.
