Publication number: 20210211055Abstract: A DC-DC converter operates in a burst mode having at least one charge cycle with a charging phase followed by a discharging phase. A charging phase is terminated when an inductor current flowing through an inductance connected to the DC-DC converter reaches a compensated peak-current threshold, wherein the compensated peak-current threshold compensates for charging-phase loop delay. A discharging phase is terminated when the inductor current reaches a compensated valley-current threshold, wherein the compensated valley-current threshold compensates for discharging-phase loop delay.Type: ApplicationFiled: January 6, 2020Publication date: July 8, 2021Inventors: Jitendra Prabhakar Harshey, Hendrik Johannes Bergveld, Edevaldo Pereira da Silva Junior, Koteswararao Nannapaneni, Uday Kumar Sajja

Patent number: 10720838Abstract: Embodiments provide forced-burst voltage regulation for burst mode direct-current-to-direct-current (DC-DC) converters in integrated circuits. The DC-DC converter generates an output voltage and operates in a burst mode to raise the output voltage to a threshold voltage. A controller is coupled to the DC-DC converter. In operation, the DC-DC converter is configured to perform the burst mode based upon a low-voltage detection for the output voltage. The DC-DC converter is further configured to perform the burst mode when a force-burst command is asserted by the controller to the DC-DC converter regardless of a state for the low-voltage detection. For one embodiment, the force-burst command is asserted as a burst control signal from the controller to the DC-DC converter to generate a long quiet period for sensitive actions. For another embodiment, the force-burst command is asserted using enable and refresh control signals to facilitate low-power operation.Type: GrantFiled: June 5, 2019Date of Patent: July 21, 2020Assignee: NXP B.V.Inventors: Jitendra Prabhakar Harshey, Olivier Trescases, Edevaldo Pereira Da Silva Junior, Stefano Pietri, Jurgen Geerlings, Hendrik Johannes Bergveld
