    • The present invention relates to a switch controlling apparatus. The switch controlling apparatus controls a main switch by using a first signal that corresponds to a current flowing to the main switch. The switch controlling apparatus includes a PWM controller for generating a control signal to control turning on/off of the main switch by using the first signal and a clock signal, and a TSD unit for changing the control signal corresponding to heat generated from the main switch. The TSD unit changes a response speed for the heat of the main switch by using the clock signal and the control signal.
