    • Disclosed are a switch control circuit, a convertor including the same, and a driving method thereof. The convertor includes an inductor storing the energy of an input terminal and supplying it to an output terminal, a first switch connected between the inductor and a ground, and a switch control circuit controlling a first switch by comparing a first voltage corresponding to the output voltage of the output terminal with a lamp voltage corresponding to a current flowing through the first switch. Here, the switch control circuit changes the slope of the lamp voltage by comparing the lamp voltage with a first reference voltage.

    • PURPOSE: A clock signal generating circuit and a power supply apparatus including the same are provided to generate a reference signal by generating a clock signal without using a large sized capacitor. CONSTITUTION: A counter(10) counts one cycle of the input clock signal by using a reference clock signal. The counter generates a count signal. A clock generator(30) inputs the count signal and the reference clock signal. The clock generator generates the count signal. The clock generator sets up a basic cycle of an output clock signal. The clock generator arranges the input clock signal to the output clock signal. [Reference numerals] (10) Counter; (20) Latch; (30) Clock generator

    • The embodiment of the present invention relates to a power supply device implemented by a high-side buck converter, a driving method, and a switch control device applied to the power supply device. The power supply device comprises a power switch including one end for receiving input power; a diode is positioned between the other end of the power switch and the ground; and a sensing resistor which is positioned between the other end of the power switch and an inductor. When a light emitting diode (LED) line is connected between the inductor and the ground, the switch control device compares a modulation sensing voltage, a high peak reference voltage, and a low peak reference voltage according to a sensing voltage generated in the sensing resistor. The switch control device controls a switching operation of the power switch according to a comparison result. The high peak reference voltage and the low peak reference voltage control the upper limit and the lower limit of LED currents which flow in the LED line.
