Patent ID: 7694163

Claim:
A system for generating and monitoring voltages a variety of different components on a common printed circuit board, such system comprising: a programmable controller; a plurality of DC/DC converters for producing voltages for the devices; a plurality of CPUs; a plurality of voltage regulators for producing voltages for the plurality of CPUs on the board, such CPU voltages being produced in accordance with VIDs provided to the regulators provided by the CPU; and wherein the programmable controller: establishes a set point voltage for such one of the DC/DC converters; sequentially monitors the produced voltages; monitors voltages produced by the regulators for the CPUs by comparing the VIDs to the voltages produced by the regulators, and if during the sequencing any one of the converters is determined by the programmable controller as producing an improper voltage or if the any one of the regulators fails to produce the voltages indicated by the VIDs, disables the board.
