Jayadevan Radhakrishnan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11594879
    Abstract: An apparatus comprises a first power supply, a second power supply, and a controller. The first power supply supplies a first input voltage to power a first input of a load over a first circuit path. The second power supply supplies a second input voltage to power a second input of the load over a second circuit path. The controller controls connectivity of the first circuit path to the second circuit path as a function of the first input voltage and the second input voltage during at least ramp up or ramp down of either or both of the first input voltage and the second input voltage.
    Type: Grant

  • Publication number: 20220320991
    Abstract: A controller for a power converter includes an output terminal operative to output a modulation signal for controlling a phase current of the power converter. A modulator is operative to generate the modulation signal such that an output voltage of the power converter follows a first portion of a load-line when load current is above a first threshold, the first portion of the load-line having a first slope that determines a rate of change of the output voltage as a function of the load current. An interface is operative to receive a temperature signal. Circuitry is operative to change the first threshold in response to receipt of the temperature signal.

  • Patent number: 11303207
    Abstract: A method of controlling a power converter includes: generating a modulation signal for controlling a phase current of a power stage of the power converter such that an output voltage of the power converter follows a load line having a slope that determines a rate of change of the output voltage as a function of load current; receiving a signal which indicates a target voltage regulation setpoint; and overriding the load line when the signal is active, such that the output voltage follows the target voltage regulation setpoint instead of the load line when the signal is present at the interface.
