ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,706,538, issued on Aug. 11, was assigned to Advanced Micro Devices Inc. (Santa Clara, Calif.).

"Multi-mode power stage architecture for pulse width modulation controller" was invented by Wei Han (Shanghai), Qi Qian (Shanghai) and Lili Chen (Shanghai).

According to the abstract* released by the U.S. Patent & Trademark Office: "A driving power stage can receive a PWM signal from the PWM controller and output a PWM signal to a secondary power stage. The secondary power stage can be turned off by the driving power stage during a light-load mode. For a single-phase application, the driving power stage can turn off a switch, causing the power stage to work as a regular power stage. Various...
