Voltage ID conversion system for programmable power supplies

A system comprising:

• generation means for generating a digital voltage identification (VID) signal including a plurality of fields, the generation means comprising:
• means for assigning a first value to a first one of the plurality of fields, the first one of the plurality of fields corresponding to a desired output voltage;
• and
• means for assigning a second value to at least one other one of the plurality of fields;
• and
• conversion means for converting the VID signal into an analog signal suitable for input to an analog-programmable power supply.

A system comprising:

• a parallel bus comprising a plurality of bus lines;
• transmission means for transmitting a plurality of fields of a digital voltage identification (VID) signal over corresponding ones of the plurality of bus lines, wherein the plurality of fields includes a first field having a first value and at least one second field having a second value that differs from the first value;
• a plurality of FETs coupled to the plurality of bus lines;
• a plurality of resistors, each of which is coupled between a corresponding one of the plurality of FETs and an intermediate node;
• a power source;
• a resistor coupled between the power source and the intermediate node;
• and
• an analog-programmable power supply having an analog input coupled to the intermediate node.
