Abstract: The present disclosure describes a system having a power supply circuit, a first regulator circuit, a second regulator circuit, and a load circuit. The power supply circuit outputs a power supply voltage. The first regulator circuit receives the power supply voltage and outputs a first regulated voltage based on the power supply voltage. The second regulator circuit receives the first regulated voltage and outputs a second regulated voltage based on the first regulated voltage. The load circuit receives the second regulated voltage and sends power requirement information (e.g., load current information) to one or more of the power supply circuit, the first regulator circuit, and the second regulator circuit. Based on the power requirement information, one or more of the power supply voltage, the first regulated voltage, and the second regulated voltage is adjusted.

Abstract: A power converter circuit included in a computer system may include a phase circuit and a sample circuit. The phase circuit compares a voltage level of the regulated power supply node to a reference voltage to generate a demand current that is used to adjust the voltage level of the regulated power supply node. The phase circuit also digitizes the demand current and stores the resultant bit stream in a memory circuit. The sample circuit generates timestamp information that points to particular storage locations in the memory circuit that correspond to trigger events, allowing the operation of the power converter circuit to be analyzed during different circumstances as well as to adjust operating parameters of the power converter circuit.
