Patent number: 10468963Abstract: 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 an increase in current flow in the inductor followed by a decrease in current flow in the inductor and before the current flow in the inductor stops, (2) discharging the capacitor causing an increase in current flow in the inductor followed by a decrease in current flow in the inductor and before the current flow in the inductor stops, repeating (1).Type: GrantFiled: December 10, 2018Date of Patent: November 5, 2019Assignee: EMPOWER SEMICONDUCTOR, INC.Inventors: David Lidsky, Timothy Alan Phillips, Parag Oak

Patent number: 10389240Abstract: A buck voltage converter is disclosed. The buck voltage generator includes a controller configured to generate one or more pulse width modulation (PWM) signals, and a plurality of serially connected switches configured to receive the PWM signals and to generate an output voltage signal at an output terminal based on the received PWM signals. The output voltage signal has an average voltage corresponding with a duty cycle of the PWM signals, a first switch of the plurality of serially connected switches has a first breakdown voltage and a second switch of the plurality of serially connected switches has a second breakdown voltage, and the first breakdown voltage is less than the second breakdown voltage.Type: GrantFiled: February 23, 2016Date of Patent: August 20, 2019Assignee: EMPOWER SEMICONDUCTORInventor: Timothy Alan Phillips

Patent number: 10389246Abstract: 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: August 29, 2017Date of Patent: August 20, 2019Assignee: Empower Semiconductor, Inc.Inventors: David Lidsky, Timothy Alan Phillips, Parag Oak
