US Patent Issued to STMicroelectronics International on Aug. 11 for "Closed loop dummy load to limit minimum operating frequency in current mode control DCDC" (French Inventors)

ALEXANDRIA, Va., Aug. 12 -- United States Patent no. 12,706,518, issued on Aug. 11, was assigned to STMicroelectronics International N.V. (Geneva).

"Closed loop dummy load to limit minimum operating frequency in current mode control DCDC" was invented by Stefano Ramorini (Milano, France) and Francesco Pinzin (Varese, France).

According to the abstract* released by the U.S. Patent & Trademark Office: "Described herein is a method of operating a DC-DC converter to avoid operating in PSM or PFM at light load, due to the possibility that uncontrolled low frequency content could be introduced. The method includes including driving a load demanding a load current with an output current, and when the output current is greater than a minimum outp...
