Patent number: 10917011Abstract: A power supply includes a power converter, a reference voltage generator, and a controller. During operation, the power converter produces an output voltage to power a load. The reference voltage generator (such as a voltage mode amplifier circuit) generates a floor reference voltage, a magnitude of which varies as a function of the output voltage. The controller compares an output voltage feedback signal (derived from the output voltage) to the floor reference voltage to produce control output to control timing of activating switches in the power converter to maintain the output voltage within a desired voltage range.Type: GrantFiled: September 24, 2019Date of Patent: February 9, 2021Assignee: Infineon Technologies Austria AGInventors: Anthony B.

Patent number: 9685923Abstract: A transmitter circuit comprises: an input, an encoder circuit, and a transmitter. During operation, the transmitter circuit receives an input signal. The encoder circuit encodes the received input signal into an encoded signal. The encoder circuit produces the encoded signal: i) to indicate changing states of the input signal, and ii) to include a supplemental transient signal with respect to the received input signal. The transmitter transmits the encoded signal from an output of the first circuit over a link to a second circuit such as a receiver circuit. A receiver decodes the encoded signal to reproduce a rendition of the input signal to control remote power supply circuitry. Presence of the supplemental transient signal in the encoded signal indicates to the receiver circuit that the first circuit actively transmits the output signal even though there may not be any change to a current state of the input signal.Type: GrantFiled: August 26, 2015Date of Patent: June 20, 2017Assignee: Infineon Technologies Americas Corp.Inventors: Anthony B.

Patent number: 9628053Abstract: During operation, a supply voltage and the reference voltage power a novel multi-level pulse generator circuit. The multi-level pulse generator circuit generates voltage pulses of varying magnitude from a respective output port. For example, the multi-level pulse generator circuit produces respective pulses to have magnitudes that fall inside and outside of a range defined by the supply voltage and the reference voltage. Expansion of the pulse magnitudes to be outside of the range as defined by the supply voltage and the reference voltage increases noise immunity and therefore enables a respective transmitter to transmit data at higher bandwidth. The multi-level pulse generator circuit can be fabricated using a set of multiple transistors of only a single type in which each of the multiple transistors in the set has a corresponding oxide breakdown voltage that is substantially less than the respective magnitude that falls outside of the range.Type: GrantFiled: August 26, 2015Date of Patent: April 18, 2017Assignee: Infineon Technologies Americas Corp.Inventors: Aswath Krishnan Krishnamoorthy, Anthony B.

Patent number: 8816661Abstract: According to example configurations as described herein, a power supply system includes a unique circuit including an analog summer circuit, an analog-to-digital converter, and a digital controller. An output voltage feedback control loop of the power supply system feeds back the output voltage to the analog summer circuit. The analog summer circuit generates an analog error voltage signal based on: i) the output voltage received from the output voltage feedback loop, ii) an analog reference voltage signal, and iii) an analog reference voltage adjustment signal. The analog reference voltage adjustment signal varies depending on a magnitude of current provided by the output voltage to the dynamic load. Accordingly, the analog summer circuit can be configured to support adaptive voltage positioning. The analog-to-digital converter converts the analog error voltage signal into a digital error voltage signal. A controller generates output voltage control signal(s) based on the digital error voltage signal.Type: GrantFiled: April 2, 2009Date of Patent: August 26, 2014Assignee: International Rectifier CorporationInventors: Anthony B.

Patent number: 8022726Abstract: A control circuit generates an output based on the first signal and the second signal by encoding the output to be a multi-state signal having at least three states. A magnitude of the multi-state signal generated by the controller varies depending on binary states of the first signal and the second signal. The controller utilizes the output (i.e., the multi-state signal) to control a switching circuit. A driver circuit receives the output generated by the control circuit. In one embodiment, the multi-state signal has more than two different logic states. The driver decodes the multi-state signal for generating signals to control switches in the switching circuit. One signal generated by the driver circuit is a pulse width modulation signal; another signal generated by the driver circuit is an enable/disable signal.Type: GrantFiled: August 18, 2010Date of Patent: September 20, 2011Assignee: International Rectifier CorporationInventors: Anthony B.
