Publication number: 20240120835Abstract: An apparatus includes first and second pluralities of switches, a controller for controlling these switches, gate-drivers for driving switches from the first plurality of switches, and first and second terminals configured for coupling to corresponding first and second external circuits at corresponding first and second voltages. During operation, the controller causes the first plurality of switches to transition between states. These transitions result in the second voltage being maintained at a value that is a multiple of the first voltage. The controller also causes the second plurality of switches to transition between states. These transitions resulting in capacitors being coupled or decoupled from the second voltage. The gate drivers derive, from the capacitors, charge for causing a voltage that enables switches from the first plurality of switches to be driven.Type: ApplicationFiled: December 19, 2023Publication date: April 11, 2024Applicant: pSemi CorporationInventors: David GIULIANO, Gregory SZCZESZYNSKI, Raymond BARRETT, JR.

Patent number: 10374512Abstract: In a power converter, each gate-driving circuit uses charge from a selected pump capacitor operate a corresponding switch. The switches transitions between different states, each of which corresponds to a particular interconnection of pump capacitors. During clocked operations, the first switch closes, thereby establishing a connection with the first pump capacitor. Prior to the first switch closing, the second switch closes.Type: GrantFiled: September 28, 2018Date of Patent: August 6, 2019Assignee: pSemi CorporationInventors: Gregory Szczeszynski, David M.

Patent number: 10263512Abstract: An apparatus for converting voltage includes terminals coupled to external circuits at corresponding voltages and a switching network having driving circuits and semiconductor switches that interconnect capacitors in successive states to one another and to the terminals. The switches interconnect some capacitors to one another through a series of switches when an activation pattern causes them to be activated. Each driving circuit has power connections, a control input, and a drive output coupled to and controlling at least one switch. A drive output of one of them couples to and drives each switch. Some of the driving circuits are powered via corresponding power connections from at least one of the capacitors such that a voltage across the corresponding power connections is less than a highest of the corresponding voltages. The terminals and the switching network are constituents of a switched capacitor converter.Type: GrantFiled: November 15, 2017Date of Patent: April 16, 2019Assignee: pSemi CorporationInventors: David Giuliano, Gregory Szczeszynski, Raymond Barrett, Jr.
