US Patent Issued to STMicroelectronics International on Oct. 27 for "Inverting buck-boost converter with ripple-based adaptive constant on-time control for AMOLED display power supply" (Italian Inventors)

ALEXANDRIA, Va., Oct. 27 -- United States Patent no. 12,776,709, issued on Oct. 27, was assigned to STMicroelectronics International N.V. (Geneva).

"Inverting buck-boost converter with ripple-based adaptive constant on-time control for AMOLED display power supply" was invented by Riccardo Pellegrini (Rho, Italy) and Alberto Cattani (Cislago, Italy).

According to the abstract* released by the U.S. Patent & Trademark Office: "A power management integrated circuit (PMIC) for AMOLED displays includes a negative voltage generator using an adaptive constant-on-time (COT) ripple-based inverting buck-boost architecture. The circuit features a ripple reconstructor that addresses load regulation issues by regenerating attenuated ripple signals from...
