Abstract
Disclosed are a pulse width modulation (PWM) signal generation circuit and a lamp control system including the same. The PWM signal generation circuit includes a pulse period control circuit configured to control charging and discharging of a first capacitor, and generate a first output signal related to a first number of times of charging of the first capacitor, a pulse width control circuit configured to control charging and discharging of a second capacitor, and generate a second output signal related to a second number of times of charging of the second capacitor, and a control logic circuit configured to determine a period of a PWM signal based on the first output signal, determine a pulse width of the PWM signal based on the second output signal, and output the PWM signal having the period and the pulse width.
