US Patent Issued to ALPHA AND OMEGA SEMICONDUCTOR INTERNATIONAL on May 13 for "Artificial dual closed-loop full-time inductor current sensing" (South Korean Inventor)

ALEXANDRIA, Va., June 12 -- United States Patent no. 12,301,091, issued on May 13, was assigned to ALPHA AND OMEGA SEMICONDUCTOR INTERNATIONAL LP (Toronto).

"Artificial dual closed-loop full-time inductor current sensing" was invented by Gilbert S. Z. Lee (Seongnam-si, South Korea).

According to the abstract* released by the U.S. Patent & Trademark Office: "A device, system, and method for inductor current sensing in a Switch Mode Power Supply (SMPS) are described. An input node signal indicating a voltage level at a switch node is sampled at a first time point and a second time point. An artificial ramp signal is generated and adjusted based on the first sampled node voltage and the second sampled node voltage to generate an output ramp ...
