Patent number: 11462990Abstract: An integrated switching regulator device has a switching mode regulator comprising an input voltage source and a switching circuit coupled to the input voltage source configured to generate a pulsed voltage from the input voltage. A low pass filter is coupled to the switching regulator and is configured to filter the pulsed voltage to provide a regulated voltage to a load. The low pass filter comprises at least two LC stages, wherein the first LC stage comprises an air cored inductor and each subsequent LC stage comprises a non-air cored inductor. The switching circuit comprises two or more switching elements configurable to operate at a switching frequency of several megahertz.Type: GrantFiled: November 28, 2018Date of Patent: October 4, 2022Assignee: UNIVERSITY OF LIMERICKInventors: Patrick Meehan, Eamon O'Malley, Karl Rinne

Patent number: 8901903Abstract: The Application is directed at arrangements at which switch mode power converters share a common load. More particularly, the application provides a masterless arrangement in which no single converter controls the operation of the other converters. This is achieved by an arrangement in which each converter attempts to share its current measurement with other converters through an arbitration scheme employed on a data line, with the winning converter providing a defacto current measurement; for example, a maximum or minimum, to the overall arrangement.Type: GrantFiled: June 15, 2010Date of Patent: December 2, 2014Assignee: Powervation LimitedInventors: Karl Rinne, Anthony Kelly, Eamon O'Malley

Patent number: 8396111Abstract: A DPWM (1) has a locked loop (4) which receives an input clock signal and provides an out-of-phase delayed clock at the output of each cell in the loop (35). A multiplexer (5) selects one of the cell outputs at any one time. This allows the DPWM (1) to have a greater resolution which would otherwise be achieved with the same input clock. The resolution is further increased using an interpolator. A programmable module (2) has a control block (20) which interfaces with external CPU and DSP hosts and transmits programmed parameters to finite state machine controllers (15), each providing an independent output.Type: GrantFiled: December 7, 2010Date of Patent: March 12, 2013Assignee: Powervation LimitedInventors: Eamon O'Malley, Karl Rinne

Publication number: 20100064124Abstract: A digital power controller (DPC, 1) controls an SMPC power stage (2). The DPC (1) interfaces with the SMPC power stage (2), and it has a system-on-a-chip (SoC) architecture including a digital signal processor (DSP, 5) for real-time control of SMPC outputs (such as output voltage) and a RISC processor (CPU, 6). An ADC (7) receives sense signals and routes them to the DSP (5), and a DPWM circuit (8) drives the SMPC. Communication with the CPU (6) is via a bus (10). The CPU (6) features include fault management and data transfers to the DSP co-processors and other peripheral blocks.Type: ApplicationFiled: November 15, 2007Publication date: March 11, 2010Inventors: Karl Rinne, Eamon O'Malley
