System Topology Options

The VID register, temperature sensor, and VID soft controller are unchangeable. Intel provides the VID soft controller as a SmartVID Controller IP to customers. The remainder of the system may have many different solutions.

The voltage regulator controller interface can be implemented as:

  • A parallel output to drive a digitally adjustable voltage regulator directly
  • A multi-wire serial interface such as I2C, SMBus*, PMBus*, or similar interface hereafter referred to as PMBus
  • A one-wire pulse width modulated (PWM) output to be used with a circuit to adjust the output of an adjustable voltage regulator

Intel provides reference designs for some of these functions. Contact your sales representative to find out what is available at this time.

Table 3.  Reference Design Availability Schedule
Voltage Regulator Controller Availability1
Parallel Intel® Quartus® Prime software version 15.0
PMBus Intel® Quartus® Prime software version 15.1
Single-wire interface (one-wire PWM) Intel® Quartus® Prime software version 16.0

The Voltage Regulator System can be implemented as:

  • A parallel input digital voltage converter.
  • A multi-wire serial voltage converter that supports the PMBus standard.
  • An adjustable voltage regulator with an analog circuit that converts the PWM signal to some means that controls the regulator output, allowing the use of standard analog voltage regulator controllers.
