Claims19
A surgical instrument, comprising:
- a handle;
- a shaft extending from said handle;
- a control system including a processor;
- a power source in communication with said control system;
- a first voltage regulator comprising a first input and a first output, wherein said first voltage regulator is configured to output a first output voltage to said first output when said first voltage regulator is in a first active state, wherein said processor is in communication with a first enabling input of said first voltage regulator, wherein said first voltage regulator is configured to switch from a first inactive state to said first active state when a first enabling voltage is applied to said first enabling input by said processor, and wherein said first voltage regulator does not output said first output voltage to said first output when said first voltage regulator is in said first inactive state;
- and
- a second voltage regulator comprising a second input and a second output, wherein said second voltage regulator is configured to output a second output voltage to said second output when said second voltage regulator is in a second active state, wherein the magnitude of said second output voltage is different than the magnitude of said first output voltage, wherein said processor is in communication with a second enabling input of said second voltage regulator, wherein said second voltage regulator switches from a second inactive state to said second active state when a second enabling voltage is applied to said second enabling input by said processor, wherein said second voltage regulator does not output said second output voltage to said second output when said second voltage regulator is in said second inactive state, and wherein said processor is configured to sequentially apply said first enabling voltage and said second enabling voltage such that said first voltage regulator and said second voltage regulator are activated sequentially.
