Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Control (Instruments)
Classification: CPC G | IPC G

Claim 13:
14. A power supply method of supplying an output current using a plurality of input voltages, the power supply method comprising:
generating a first output current using a first input voltage among the plurality of input voltages;
comparing the first input voltage to a first reference voltage to generate a first comparison result;
generating a comparison signal corresponding to the first comparison result;
generating a digital code indicating accumulated information of the comparison signal based on the comparison signal;
based on the digital code indicating that the first input voltage is higher than a first reference voltage, supplying power using the first output current without using a second output current; and
based on the digital code indicating that the first input voltage is lower than the first reference voltage, generating the second output current corresponding to the digital code using a second input voltage among the plurality of input voltages, and supplying power using the first output current and the second output current.
