Abstract:
The power supply device includes a power switch including one terminal to which an input voltage is transferred; an inductor including one terminal connected to another terminal of the power switch; a diode connected between a ground and a floating ground; a sensing resistor connected between the floating ground and the one terminal of the inductor. A switch controller compares a modulation sensing voltage depending on a sensing voltage generated from the sensing resistor with a high peak reference and a low peak reference when a LED string is connected between an inductor and the ground. The switch controller controls a switching operation of a power switch according to the comparison result. The high peak reference and the low peak reference are references for controlling an upper limit and a lower limit of an LED current flowing through the LED string, respectively.

Claim (Index 7):
The switch controller circuit of  claim 5 , wherein the sine-wave generator is configured to:\n serially arrange a first plurality of digital values indicating the first reference varying for each sine wave period of the clock signal based on the zero crossing detection signal to generate the first digital signal; and serially arrange a second plurality of digital values indicating the second reference varying for each sine wave period of the clock signal based on the zero crossing detection signal to generate the second digital signal.
