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 11):
The switch controller circuit of  claim 9 , wherein the switch control signal generation circuit comprises:\n a first comparator having an inverting input coupled to the first reference and a non-inverting input coupled to the modulation sensing voltage; a second comparator having a non-inverting input coupled to the second reference and an inverting input coupled to the modulation sensing voltage; and an SR flip-flop having a set input coupled to the output of the first comparator and a reset input coupled to the output of the second comparator, wherein the switch control signal is produced using an output of the SR flip-flop.
