Abstract
A power delivery device includes a socket to couple and deliver power to an electronic component. A voltage control sensor is coupled to the socket to sense an output voltage at the socket and to provide negative feedback control. An impedance of the socket and an associated baseboard is incorporated into the negative feedback control and may help compensate for voltage droop in the output voltage.
Claims17
An apparatus comprising:
- a socket having an impedance to couple and deliver power to an electronic component;
- a voltage control sensor coupled to the socket to sense an output voltage at the socket and to provide negative feedback control, whereby an impedance of the socket is incorporated into the negative feedback control.
A power delivery device comprising:
- a socket to receive a CPU;
- and
- a voltage regulator to provide regulated voltage to the CPU through the socket, the voltage regulator comprising:
- a voltage control sensor coupled to the socket to sense an output voltage at the socket and to provide negative feedback control;
- and
- a first decoupling capacitor coupled to a junction between the socket and the CPU.
