Abstract
Disclosed is a pulse width modulation signal generation circuit including a charging control circuit connected to and located between a first node connected to a capacitor and a voltage line that supplies an operating voltage, a discharging control circuit connected to and located between the first node and ground, a comparison circuit that generates a comparison signal by comparing a first reference voltage and a second reference voltage with a voltage of the first node, and a control logic circuit that generates a pulse width modulation signal whose level changes based on a level change of the comparison signal and determines a level change timing for the activation of the charging control signal and the discharging control signal using the level change of the comparison signal; and a lamp control system including the pulse width modulation signal generation circuit.
