The Voltage Regulator Module (VRM) concept was developed by Intel to guide the design of dc-dc converters that supply the required voltage and current to a Pentium® microprocessor. The maximum voltage is determined by the five-bit VID (Voltage Identity) code provided to the VRM. The five-bit, five-pin VID code connects the power supply controller to the corresponding pins on the microprocessor. Therefore, the internal coding in the microprocessor controls the dc voltage applied to processor. VRM guidelines are intended for a special module, usually a small circuit board, that plugs into the computer system board and supplies power for the microprocessor.
