Patent number: 11223338Abstract: In one embodiment, an amplifier circuit may be configured with an output transistor that forms an output current and an output voltage at an output. The amplifier circuit may also include a reference circuit that may be configured to form a reference current that is substantially proportional to the output current. An embodiment of the reference circuit may also be configured to control a transistor to sink current from the output in response changes in the reference current.Type: GrantFiled: March 10, 2020Date of Patent: January 11, 2022Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Martin Podzemny

Patent number: 11036248Abstract: A voltage regulator circuit may include a first loop that forms a reference signal that substantially does not vary in response to the output voltage, the reference circuit may also be configured to form a control signal that is representative of changes in the reference signal. The voltage regulator circuit may also include a second loop configured to form a value of a control electrode of an output transistor according to the control signal and wherein the output circuit is configured to change a value of the control electrode according to a difference between the output voltage and the reference signal.Type: GrantFiled: March 2, 2020Date of Patent: June 15, 2021Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Martin Podzemny

Patent number: 10833575Abstract: In one embodiment, a controller for a power supply may be configured to operate as a quasi-resonant controller while operating in a discontinuous current mode and to operate as one of a pulse width or pulse frequency modulation controller while operating in a continuous current mode. The controller may have an embodiment that varies a frequency of the switching drive signal around a center frequency while operating in the continuous current mode, and varies a value of a current sense signal but not vary the frequency of the switching drive signal around a center frequency while operating in the discontinuous current mode.Type: GrantFiled: December 19, 2018Date of Patent: November 10, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Martin Podzemny, Vaclav Peroutka

Patent number: 10622901Abstract: A power converter includes a primary controller having a control voltage terminal for receiving electrical power and a monitor terminal electrically coupled to an input sensing node with an input voltage varying periodically below a first start threshold voltage to define valleys. The power converter includes a first current source configured to drive a first electrical current from the monitor terminal to the control voltage terminal in response to the input voltage being less than the first start threshold voltage. A delay timer delays driving the first electrical current to center a supply time interval within a valley. A second current source drives a second electrical current from the monitor terminal to the control voltage terminal in response to the input voltage being less than a second start threshold voltage to reduce an impedance of the monitor terminal when the input voltage is in a valley.Type: GrantFiled: March 27, 2019Date of Patent: April 14, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Petr Papica, Martin Podzemny, Martin Kejhar, Jakub Tomanek
