  • Circuit and method for generating PWM signal for DC-DC converter using dimming signal and LED driving circuit for backlight having the same
    Patent number: 8581511
    Abstract: A pulse width modulation (PWM) signal generating circuit that generates a PWM signal for a DC-DC converter using a dimming signal is provided. The PWM signal generating circuit includes a normal PWM signal generator configured to generate a normal PWM signal based on a clock signal provided to the DC-DC converter, and a compensation PWM signal generator configured to generate a compensation PWM signal based on the clock signal and the dimming signal.
