Abstract
A display apparatus and a power circuit device thereof are provided. The power circuit device includes: a transforming unit which outputs a first output current and a second output current in response to change of an input current; a first switching unit which switches to allow the input current to be selectively input; a first switch control unit which controls the first switching unit so that an operation voltage of the display apparatus reaches a first target value; a second switching unit which switches to allow the second output current to be selectively output; a backlight driving unit which drives the backlight based on the second output current; and a second switch control unit which controls the second switching unit so that a driving voltage of the backlight reaches a second target value.
