Abstract
A voltage regulator for use with switchable graphics processors. The voltage regulator includes a graphics processor mode selection control input. By providing the graphics processor mode selection control input it is possible to save pins for a parallel voltage identification (PVID) input (e.g., a 2-bit PVID input). The voltage regulator further includes a PVID input to allow the voltage regulator to switch a detection input to either a SVID type input or a PVID type input. The voltage regulator further includes voltage shifter for a PVID detection circuit.
