Abstract: A power management unit of a mobile terminal. The power management unit includes a DC-DC converter configured to convert an input voltage into first and second output voltages, the mobile terminal also includes a first boosting circuit configured to boost the first output voltage to a first boosting voltage having a first polarity and to selectively apply the first boosting voltage to a display module of the mobile terminal. The mobile terminal also includes a second boosting circuit configured to boost the second output voltage to a second boosting voltage having a second polarity that is opposite to the first polarity of the first boosting voltage, and to selectively apply the second boosting voltage to the display module of the mobile terminal.
