    • A switching controller, a switch control method, a converter and a driving method using the switch controller and the switch control method are provided to prevent the reduction of a peak value of a current flowing in the switch by the temperature rise during a soft start setting period. In a switch controller(400) of a converter, a soft start signal generator generates a first voltage by using an input signal, and generates a soft start signal increased during a predetermined period from an initial operation of the converter. A PWM(Pulse Width Modulation) controller controls an switching operation of the switch by using the signal with small value of a feedback signal and a soft start signal and the current flowing in the switch.

    • A switching mode power supply and a driving method thereof are provided to reduce an EMI(electromagnetic interference) by maintaining a constant switching frequency modulation range irrespective of an input voltage. A power supply unit(100) includes a switching transistor which is coupled with a primary coil of a transformer. The transformer rectifies an input AC voltage to generate an input DC voltage and changes the input DC voltage. The power supply unit supplies electrical power to a secondary portion of the transformer according to the operation of the switching transistor. A switching controller(400) receives a feedback voltage corresponding to a secondary voltage of the transformer, a sensor signal, and a first signal, and turns on/off the switching transistor. The first signal corresponds to a voltage difference between first and second electrodes of the switching transistor. The switching controller generates a current signal corresponding to the first signal and sets a threshold period, where the current signal is greater than a reference current value. The switching controller turns on the switching transistor during an interval between the threshold period and a variable delay period.

    • A switch controlling apparatus is provided to prevent a main switch from being damaged by turning off the main switch when the main switch is overheated. A PWM(Pulse Width Modulator) controller(11) generates a control signal for controlling switching operation of a main switch(M) by using a first signal and a clock signal(CLK). A thermal blocking unit(13) modifies the control signal corresponding to heat generated from the main switch. The thermal blocking unit decides a response speed for the heat of the main switch by using the clock signal and the control signal. The thermal blocking unit increases the response speed for the heat of the main switch when the control signal turns off the main switch due to the clock signal.
