A LEVEL TRANSLATOR FOR SUPPORTING THE FUNCTION OF AUTOMATIC VOLTAGE CONTROL

摘要

A level translator supporting an automatic voltage adjusting function is provided to transform external input voltage into a level of specified voltage required from a mobile terminal and apply the transformed external input voltage to the mobile terminal when power for data communication is applied to the mobile terminal. A version signal processor(110) receives a version signal having information for the specified voltage from the mobile terminal(200) and processes the received version signal when the power for the data communication is applied to the mobile terminal. A voltage controller(120) determines the level of the voltage applied to the mobile terminal by using a process result of the version signal processor. A constant voltage transforming/outputting part(130) transforms the external input voltage into the specified voltage of the mobile terminal and outputs the transformed external input voltage to the mobile terminal.
