Regulator Switch Array - A simplified explanation of the abstract

This abstract first appeared for US patent application 17661509 titled 'Regulator Switch Array

Simplified Explanation

The abstract describes a voltage regulator circuit used in a computer system.

  • The circuit includes a control circuit and a switch array with multiple switch circuits.
  • Different groups of switch circuits are connected between an input power supply node and regulated power supply nodes.
  • The control circuit compares the voltages of the regulated power supply nodes to reference voltages.
  • Based on the comparison results, the control circuit opens and closes specific switch devices in the different groups of switch circuits.
  • The purpose is to maintain desired voltages on the regulated power supply nodes.


Original Abstract Submitted

A voltage regulator circuit included in a computer system may employ a control circuit and a switch array that includes multiple switch circuits. Different groups of switch circuits that include respective groups of switch devices are coupled between an input power supply node and corresponding regulated power supply nodes. To maintain desired respective voltages on the regulated power supply nodes, the control circuit compares the voltages of the regulated power supply nodes to corresponding reference voltages and, based on results of the comparisons, opens and closes various ones of the switch devices included in the different groups of switch circuits.
