Power sourc system for microprocessor

Abstract

A power supply system that provides a relatively constant voltage to a microprocessor with low inductance and low impedance. The system includes a motherboard (130), an integrated circuit (IC) (140) mounted on one side of the motherboard, a capacitor bank (346) mounted on the opposite side of the motherboard, and a side of the motherboard opposite the IC on the converter (110). The IC contains a microprocessor that draws power from a converter and capacitor bank. Short current paths between components are achieved by placing the converter and capacitor bank on the side of the motherboard opposite the IC. By shortening the current path, the system reduces the inductance and impedance created by the electrical traces. The elements of the system are pressed together. Instead of using long traces or dedicated parts to connect the converter and the main board, a pressure interface (116) is provided between the converter, capacitor bank and main board. The pressure interface consists of conductive material that facilitates the conduction of electricity between different components. The pressure interface prevents excessive inductance and impedance between the converter, capacitor bank and motherboard.

Description

technical field [0001] The present invention generally relates to an improvement in the power supply of an electronic circuit, and in particular to an improved power delivery system for a microprocessor. Background technique [0002] Current microprocessors and associated integrated circuits generally require higher power supplies than previous microprocessors and integrated circuits. Along with higher power requirements, current microprocessors typically require higher currents. For example, many microprocessors require approximately 100 amps to operate properly. Additionally, modern microprocessors switch current at very high rates, such as switching from 0 amps to 100 amps in 1 microsecond or less. In general, due to the high speed at which modern microprocessors operate, they often require higher power supplies than previously required. [0003] Typically, a microprocessor operates at a lower voltage, such as 3.3 volts, while running continuousl...

AI Technical Summary

Problems solved by technology

The system is usually more expensive than other systems because of these additional components used

Furthermore, the system presents problems when these elements require maintenance or repair

Due to the use of additional specialized components and components, when one of these specialized components fails, other replacement components cannot be replaced

Also, the presence of different components will reduce the reliability of the system

Every add-on and part is prone to problems

Usually, if one component or component fails, the entire system will not work

As a result, more elements and components are present, increasing the risk of system problems
