An electronic device includes a power management device configured to supply a plurality of input voltages; a power module configured to generate an output voltage using at least one of the plurality of input voltages, and to output the generated output voltage; and a system load configured to operate by receiving the output voltage, wherein the power module includes: a first power module configured to receive a first input voltage from the power management device, and to generate a first output current using the first input voltage; and a second power module configured to receive a second input voltage from the power management device, and to generate a second output current using the second input voltage based on the first input voltage being lower than a first reference voltage.

Power supply method using a plurality of voltage sources and electronic device using the same

Disclosed is a power module which includes a first power module that generates a first output current based on a first input voltage, a second power module that generates a second output voltage based on a second input voltage, generates a second output current based on the second output voltage, and generates the second output current when a level of the first input voltage is smaller than a level of a reference voltage, and a voltage controller that generates a feedback signal for regulating at least one of the level of the first input voltage and a level of the second input voltage based on current information about a current flowing in the power module.

Power module and electronic device therewith

A method of providing a service using a keypad is provided. The method includes displaying a text box and a keypad on an executed screen, inputting a start identifier according to a selection of a smart conversion button of the keypad, inputting a command after the identifier, inputting a termination identifier after the command, performing an intelligent service according to the command when the termination identifier is inputted, and outputting a result according to the intelligent service in the text box.

Method and apparatus for providing intelligent service using inputted character in a user device

A method and an apparatus for executing a user function using voice recognition. The method includes displaying a user function execution screen; confirming a function to be executed according to voice input; displaying a voice command corresponding to the confirmed function on the user function execution screen; recognizing a voice input by a user, while a voice recognition execution request is continuously received; and executing the function associated with the input voice command, when the recognized voice input is at least one of the displayed voice command.

Method and apparatus for executing a user function using voice recognition

Provided are a method and an apparatus for performing exact start and end recognition of voice based on video recognition. The method includes determining whether a speech starts based on at least one of first video and audio data before conversion into a voice recognition mode, converting into the voice recognition mode and generating second audio data including a voice command, when it is determined that speech starts, and determining whether the speech is terminated based on at least one of second video and audio data after conversion into the voice recognition mode.
