Claim 19:
20. The display device according to claim 15, wherein the power supply device comprises:
a current sensor configured to sense the power current through the second electrode of the third transistor, the second electrode of the fourth transistor, the second electrode of the sixth transistor, and provide sensing information based on the sensed power current;
a converter selector configured to generate a first select signal, a second select signal, and a third select signal based on the sensing information;
feedback resistors connected in series to the output terminal;
a control voltage generator configured to generate a control voltage based on a feedback voltage received from a node between the feedback resistors;
a first gate driver configured to control turning on or off of the fifth transistor and the sixth transistor based on the first select signal, the sensing information, and the control voltage;
a second gate driver configured to control turning on or off of the first transistor and the third transistor based on the second select signal, the sensing information, and the control voltage; and
a third gate driver configured to control turning on or off of the second transistor and the fourth transistor based on the third select signal, the sensing information, and the control voltage.
