Patent number: 10715043Abstract: A single inductor multiple output SIMO power converter and method are presented. The converter has a single inductor and at least two output terminals which are denoted as first output terminal and second output terminal. The SIMO power converter also has a first switching element and a second switching element. The first switching element is coupled between an output terminal of the inductor and the first output terminal of the SIMO power converter. The second switching element is coupled between the output terminal of the inductor and the second output terminal of the SIMO power converter. The SIMO power converter also has a control circuit to detect an overload condition at the first output terminal, and to generate control signals for controlling the switching of the first switching element and the second switching element based on the detected overload condition.Type: GrantFiled: April 3, 2019Date of Patent: July 14, 2020Assignee: Dialog Semiconductor (UK) LimitedInventor: Lourans Samid

Patent number: 8829883Abstract: In one embodiment, a method includes generating a drive current. Generation of the drive current results in a first leakage current, and the drive current and first leakage current each flow into a first node. The method also includes generating a second leakage current and amplifying the second leakage current to generate a leakage-compensation current. The leakage-compensation current flows away from the first node.Type: GrantFiled: September 9, 2011Date of Patent: September 9, 2014Assignee: Atmel CorporationInventor: Lourans Samid
