Patent number: 10505454Abstract: The overall performance of single input multiple output (SIMO) switching DC-DC power converters may be improved by controlling power and output switches to adjust inductor current delivered to one output while maintaining substantially constant the current delivered to other outputs, thereby reducing cross regulation interference across outputs. Power converter systems of this disclosure may be configured to calculate an inductor current value and a duty cycle value based on voltages at each of the voltage outputs. The power converter systems may be configured to control at least one main power switch to increase or decrease the current in the inductor based on the calculated inductor current value. Additionally, the power converter systems may be configured to control at least one output power switch to divert current from the inductor to one of the plurality of output nodes based on the calculated duty cycle value.Type: GrantFiled: December 19, 2018Date of Patent: December 10, 2019Assignee: Cirrus Logic, Inc.Inventors: Xin Zhao, John L.

Patent number: 10249283Abstract: The handling of disturbances to audio signals may be improved with an adaptive noise cancellation (ANC) system that performs tone suppression and howl suppression in a collaborative manner. Such ANC systems may be configured to detect a first tone in an input signal at a first tone frequency and extract the detected first tone from the input signal. The ANC systems may also be configured to adaptively filter the extracted first tone to generate a second tone that has a magnitude that is approximately equal to a magnitude of the extracted first tone and a phase that is approximately opposite the phase of the extracted first tone. The ANC systems may be further configured to add the second tone to an intermediate signal that is based, at least in part, on the input signal to generate the output signal.Type: GrantFiled: August 4, 2017Date of Patent: April 2, 2019Assignee: Cirrus Logic, Inc.Inventors: Dayong Zhou, Yang Lu, Jeffrey D.

Patent number: 9713206Abstract: An LED lighting device includes an auxiliary power supply that supplies power to a control circuit of the LED lighting device that receives an input from a terminal of a light-emitting diode (LED) string of the lighting device that has a substantially lower voltage than the line voltage to which the lighting device is connected. The terminal may be within the LED string, or may be an end of the string. A linear regulator may be operated from the voltage drop across a number of the LEDs in the string so that the energy wasted by the auxiliary power supply is minimized. In other designs, the auxiliary power supply may be intermittently connected in series with the LED string only when needed. The intermittent connection can be used to forward bias a portion of the LED string when the voltage supplied to the LED string is low, increasing overall brightness.Type: GrantFiled: July 16, 2015Date of Patent: July 18, 2017Assignee: PHILIPS LIGHTING HOLDING B.V.Inventors: John L.

Patent number: 9504111Abstract: A line-frequency determining circuit for coupling to the output of a thyristor-switched dimmer that determines a line-frequency of an AC power source that supplies an input to the thyristor-controlled dimmer permits accurate control of periodic probing of the dimmer output. The probing is performed to predict zero-cross times of the AC power source that, in turn, are used to determine a dimming control value of the thyristor-switched dimmer. A minimum conductance is applied across the output of the dimmer during the probing intervals that begin at the turn-on time of the dimmer and last until enough information has been gathered to correctly predict a next zero crossing of the AC line voltage that supplies the input of the dimmer. The probing can be performed at intervals of an odd number of half-cycles of the AC line frequency so that internal dimmer timer operation is not affected by DC offset.Type: GrantFiled: December 4, 2014Date of Patent: November 22, 2016Assignee: KONINKLIJKE PHILIPS N.V.Inventors: Eric King, John L.

Patent number: 9496855Abstract: A bipolar junction transistor (BJT) may be used in a power stage DC-to-DC converter, such as for LED-based light bulbs. The BJT may be switched on and off from a controller coupled to two terminals of the BJT. Through the two terminals, the control IC may dynamically adjust a reverse recovery time period of the BJT. The reverse recovery time period may be adjusted by changing an amount of base charge that accumulates on the BJT. Additional, the reverse recovery may be controlled through the use of a reverse base current source applied to the BJT after beginning switching off the BJT.Type: GrantFiled: July 28, 2014Date of Patent: November 15, 2016Assignee: CIRRUS LOGIC, INC.Inventors: Siddharth Maru, John L.
