Patent number: 10938304Abstract: Various embodiments provide a direct current (DC)-DC converter circuit. The DC-DC converter circuit includes a control circuit to switch the DC-DC converter circuit between a charge state, a discharge state, and a tri-state mode. As part of a first control loop, the control circuit may switch the DC-DC converter between the charge state and the discharge state based on the output voltage to provide the output voltage with the target voltage level. Additionally, as part of a second control loop, the control circuit may switch the DC-DC converter between the charge state and the discharge state based on the current through an inductor of the DC-DC converter. The second control loop may provide overcurrent protection for the DC-DC converter. Other embodiments may be described and claimed.Type: GrantFiled: June 20, 2019Date of Patent: March 2, 2021Assignee: Intel CorporationInventors: David Herbison, Marc Hesener, Tobias Werth, Stefan Guenther

Patent number: 10622898Abstract: Systems, methods, and circuitries for regulating voltage supplied to a power amplifier are disclosed. In one example, a buck-boost control system is configured to control a buck-boost converter to operate in either a buck mode or a boost mode. The system includes compensator circuitry configured to determine a target current based on a difference between a target voltage and a regulated output voltage of the buck-boost converter and determine a tolerance current that, with the target current, defines a range of expected coil current for the present operating mode. Based on the difference between the target voltage and the regulated output voltage, a charge control signal or a discharge control signal is generated for the converter to cause the coil current to approach the target current. Mode control circuitry is configured to switch the buck-boost converter to the other operating mode when the coil current reaches the tolerance current.Type: GrantFiled: December 28, 2018Date of Patent: April 14, 2020Assignee: Intel CorporationInventors: Stephan Henzler, David Herbison, Emil Neborovski, Thomas Piorek, Yifan Wang, Holger Wenske, Tobias Werth

Patent number: 9389628Abstract: A digitally controlled buck boost regulator includes an H-bridge circuit including a plurality of switches configured to receive an input voltage signal and generate an output voltage signal based on the input voltage signal and switching signals provided thereto. A controller generates a pulse width modulation (PWM) control value in response to a value of the output voltage signal, and a quantizer/mapper receives the PWM control value and provides a first mapping to a mapped PWM control value if the PWM control value is outside a predetermined range of PWM control values, and generates a second mapping to a mapped PWM control value if the PWM control value is within the predetermined range. A digital pulse width modulator is configured to generate switching signals based on the mapped PWM control value, and provide the generated switching signals to the H-bridge circuit.Type: GrantFiled: March 12, 2013Date of Patent: July 12, 2016Assignee: Intel Deutschland GmbHInventor: David Herbison

Publication number: 20080052454Abstract: A storage system that may include one or more memory devices, a memory interface device corresponding to one or more of the memory devices, which are organized in sections, and a section controller. In this system, a data request for the data may be received over a communications path by a section controller. The section controller determines the addresses in the memory devices storing the requested data, transfers these addresses to those memory devices storing the requested data, and transfers an identifier to the memory interface device. The memory device, in response, reads the data and transfers the data to its corresponding memory interface device. The memory interface device then adds to the data the identifier it received from the section controller and forwards the requested bits towards their destination, such that the data need not pass through the section controller.Type: ApplicationFiled: May 15, 2007Publication date: February 28, 2008Inventors: Melvin Bullen, Steven Dodd, William Lynch, David Herbison

Publication number: 20070237009Abstract: A memory access scheme employing one or more sets of shift registers interconnected in series to which data may be loaded from or written into one or more memory devices. That is, data from the memory devices may be parallel loaded into the sets of shift registers and then serially shifted through the shift registers until it is output from the sets of shift registers and transferred to its destination. Additionally, the data may be read from and loaded into the memory devices to/from the sets of shift registers such that the shifting of the shift registers is uninterrupted during the reading and/or loading of data. Additionally, data from the memory devices may be loaded into two or more parallel chains of shift registers and then serially shifted through the shift register chains.Type: ApplicationFiled: May 29, 2007Publication date: October 11, 2007Inventors: William Lynch, David Herbison
