Summary:PURPOSE: An apparatus and method for generating multichannel pulse width modulation signals and an LED system including the same are provided to stabilize the level of a voltage applied to a plurality of loads by providing a plurality of pulse width modulation signals which distribute on-timing of a plurality of loads. CONSTITUTION: Information about a pulse width is received(S1010). A plurality of pulse width modulation signals are outputted based on the received information about the pulse width(S1020). At least one pair of pulse width modulation signals with phase difference corresponding to the difference of the pulse width and an output cycle are outputted.
