Pulse-width modulation voltage identification interface

A system, comprising:

• an integrated circuit device that generates a pulsed signal having a particular duty cycle that is selected from a group of defined duty cycles;
• and
• a voltage regulator circuit that is coupled to the integrated circuit device via a single control wire and receives the pulsed signal having the particular duty cycle from the integrated circuit device via the single control wire, wherein the voltage regulator circuit generates a voltage supply signal that corresponds to the particular duty cycle of the pulsed signal by decoding the pulsed signal to determine a particular voltage level that corresponds to the particular duty cycle.

A method for operating an integrated circuit device to control a voltage regulator circuit, the method comprising:

• using the integrated circuit device, generating a pulsed signal having a particular duty cycle that is based on information on temperature associated with the integrated circuit device and one or more voltage level adjustments based on one or more blown fuses within the integrated circuit device;
• and
• using the integrated circuit device, transmitting the pulsed signal having the particular duty cycle to the voltage regulator.
