  • Scalable power delivery system
    Patent number: 11983063
    Abstract: A power delivery system included in a computer system using multiple power converter circuits to generate respective voltage levels on multiple power supply nodes. The power delivery system includes a step-down power converter circuit that generates a voltage level for use by host and follower power converter circuits. The host power converter circuit generates an external demand current that is shared by multiple follower power converter circuits to regulate the voltage level on the multiple power supply nodes. The power delivery system can be scaled to different platforms of the computer system by adjusting the number of follower power converter circuits.

  • Scalable Low Dropout Regulator
    Publication number: 20230400869
    Abstract: A regulator circuit included in a computer system may include a control circuit and multiple pass circuits that source respective supply currents to a regulated power supply node by adjusting respective conductance values between an input power supply node and the regulated power supply node. The number of pass circuits can be adjusted on a design-by-design basis based on a threshold load current for the regulator circuit or on a threshold conductance between the input power supply node and the regulated power supply node. The control circuit adjusts the respective conductance values using a combination of respective sense currents generated by the multiple pass circuits along with a reference voltage and a voltage level of the regulated power supply node.
