PURPOSE: An inverter circuit for an LCD backlight is provided to control an output current of a lamp by supplying a driving pulse corresponding to a compensation current to an output current deviation controller. CONSTITUTION: First and second transformers(102,104) comprise a first winding and a second winding. An output current deviation controller(106) is electrically connected to the output terminal of the first and second transformers. The output current deviation controller controls the output current of the lamp by comparing the output signals of the first and second transformers. A driving pulse supply unit(108) is electrically connected to the first winding of the first and second transformers and the output current deviation controller. The driving pulse supply unit supplies the driving pulse corresponding to the compensation current to the output current deviation controller. |
