Abstract: 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.
