Abstract
A voltage regulator includes circuitry for regulating a voltage output of the voltage regulator and a snubber circuit. The snubber circuit includes a switching device which is controlled to electronically connect or disconnect the snubber circuit with the circuitry of the voltage regulator device. The switching device may be controlled by a controller based on one or more parameters indicating a load of the voltage regulator device.
Claims19
A voltage regulator comprising:
- voltage regulator circuitry;
- a snubber circuit including a switching device, the switching device configured to electrically connect or disconnect the snubber circuit with the voltage regulator circuitry based upon a snubber control, and
- the snubber controller configured to provide the snubber control based on one or more detected values including a power output of the voltage regulator circuitry or a temperature in the vicinity of the switching circuitry.
(canceled)
7-8. (canceled)
A method comprising:
- performing voltage regulation with switching circuitry;
- monitoring the switching circuitry;
- and
- comparing data from the monitoring with one or more thresholds at a snubber controller, wherein the snubber controller is configured to control a switching device of a snubber circuit to electrically connect the snubber circuit to a voltage output of the switching based on the comparison of the data with the one or more thresholds, the one or more thresholds including a power output of the switching circuitry or one or more temperature values.

A semiconductor comprising:
- voltage regulator circuitry including switching circuitry;
- a snubber circuit including a switching device, the switching device configured to electrically connect or disconnect the snubber circuit with the switching circuitry based upon a snubber control;
- and
- a snubber controller configured to compares data to a threshold and provides the snubber control to the switching device based on the comparison of the data to the threshold, the data including on one or more detected values including a power output of the voltage regulator circuitry or a temperature in the vicinity of the switching circuitry.
