Title: Innovations of Chin-Jui Liu

Introduction

Chin-Jui Liu is a prominent inventor based in Xizhi, Taiwan. He has made significant contributions to the field of power supply systems and voltage regulation. With a total of 13 patents to his name, Liu's work has had a substantial impact on the efficiency and performance of information handling systems.

Latest Patents

One of Liu's latest patents is titled "System and method for selecting a voltage on a barrel adapter interface." This invention provides a method and system for supplying power at a voltage selected from a plurality of voltages. The system initially receives power at a first voltage and communicates with an AC adapter to identify if it supports other voltages. If a more efficient voltage is available, the system negotiates a power supply contract to operate at that voltage. When the system powers down, it resets to the initial voltage.

Another notable patent is "Monolithic Pstages and methods for voltage regulators." This invention includes monolithic power stage packages designed to enhance thermal performance, reduce noise, and minimize package footprint compared to conventional designs. The packages feature larger conductive pads for improved heat transfer, resulting in lower operating temperatures and increased power output. Additionally, the monolithic Pstage package can automatically detect and select between higher and lower power applications.
