Abstract
Large semiconductor ICs provide the processing power for billions of electronic devices used in every facet of modern life. Multiphase voltage regulator systems are the most common means of providing the current required for these CPUs, GPUs, and ASICs. Contemporary designs require 8, 12, 16, and potentially even higher phase counts. Existing designs require each phase to have a dedicated PWM signal terminal and provide an independent current feedback line to the multiphase VR controller for current sharing purposes; this requirement drastically increases the pin count of the controller and creates congestion in PCB routing. Our new idea allows the VR controller to send only one PWM signal to all power stages and moves the current sharing function to the power stage element, thereby reducing the cost of the controller and the complexity of the PCB.
