Multi-Phase Power Converter with External Driver - A simplified explanation of the abstract
This abstract first appeared for US patent application 18156788 titled 'Multi-Phase Power Converter with External Driver
Simplified Explanation
The abstract describes a power converter circuit used in a computer system to regulate the power supply voltage for other circuits. The power converter includes a primary control circuit that activates multiple phase circuits through driver circuits, which are connected to a power supply node using inductors. Some of the driver circuits are located on a separate integrated circuit from the primary control circuit and the multiple phase circuits.
- The power converter circuit is designed to regulate the power supply voltage in a computer system.
- It includes a primary control circuit that selectively activates multiple phase circuits.
- The multiple phase circuits are coupled to driver circuits, which are connected to a power supply node using inductors.
- Some of the driver circuits are located on a separate integrated circuit from the primary control circuit and the multiple phase circuits.
Potential Applications
- This power converter circuit can be used in various computer systems, including desktops, laptops, servers, and embedded systems.
- It can also be applied in other electronic devices that require regulated power supply voltages.
Problems Solved
- The power converter circuit solves the problem of regulating the power supply voltage for other circuits in a computer system.
- It addresses the challenge of efficiently activating multiple phase circuits through driver circuits.
Benefits
- The power converter circuit provides a reliable and efficient solution for regulating power supply voltages in computer systems.
- By selectively activating multiple phase circuits, it optimizes the power conversion process and improves overall system performance.
- The integration of driver circuits on a separate integrated circuit enhances flexibility and scalability in system design.
