Abstract
A power circuit includes a plurality of regulators and a plurality of in-rush current controllers. The plurality of regulators is coupled to an external power voltage and configured to adjust a level of an input voltage to generate a plurality of internal power voltages. The plurality of in-rush current controllers is configured to provide the input voltage to the plurality of regulators, the input voltage corresponding to an increasement voltage. The increasement voltage has a level rising at a preset rate until the plurality of internal power voltages all reach a target level.
Claims20
A power circuit comprising:
- a plurality of regulators coupled to an external power voltage and configured to adjust a level of an input voltage to generate a plurality of internal power voltages;
- and
- a plurality of in-rush current controllers configured to provide the input voltage to the plurality of regulators, the input voltage corresponding to an increasement voltage, the increasement voltage having a level rising at a preset rate until the plurality of internal power voltages all reach a target level.
A semiconductor device comprising:
- a data device configured to store a data entry or process and modify the data entry;
- and
- a power circuit configured to supply a plurality of internal power voltages to the data device based on an external power voltage input through a pin or a pad,
- wherein the power circuit comprises a plurality of in-rush current controllers configured to provide an increasement voltage having a level rising at a preset rate, instead of a reference voltage having a constant level, until a timing when the plurality of internal power voltages reach a target level the latest.
