Patent number: 12556085Abstract: A switched-mode power regulator circuit has four solid-state switches connected in series and a capacitor and an inductor that regulate power delivered to a load. The solid-state switches are operated such that a voltage at the load is regulated by repetitively (1) charging the capacitor causing a current to flow in the inductor and (2) discharging the capacitor causing current to flow in the inductor. The power regulator circuit may be configured to operate with zero current switching at frequencies in the range of 100 MHz, enabling it to be fabricated on a unitary silicon die along with the load that it powers.Type: GrantFiled: December 6, 2022Date of Patent: February 17, 2026Assignee: Empower Semiconductor, Inc.Inventors: David Lidsky, Timothy Alan Phillips

Patent number: 12470141Abstract: A switched-mode power regulator circuit has four solid-state switches connected in series and a capacitor and an inductor that regulate power delivered to a load. The solid-state switches are operated such that a voltage at the load is regulated by repetitively (1) prefluxing the inductor then charging the capacitor causing an increased current to flow in the inductor and (2) prefluxing the inductor then discharging the capacitor causing increased current to flow in the inductor. The inductor prefluxing steps enable the circuit to provide increased output voltage and/or increased output current.Type: GrantFiled: December 13, 2022Date of Patent: November 11, 2025Assignee: Empower Semiconductor, Inc.Inventors: David Lidsky, Timothy Alan Phillips, Parag Oak
