BD9478F is PWM pulse generator for LCD panel. ThisIC compares triangle waveform which is generatedinside IC and external DC signal, and generates aPWM pulse. This PWM pulse is provided to LED driverand controls LED grayscale. PWM pulse frequencycan be synchronized to external signal frequencyinputted to SYNC terminal. Even if this frequency getsout of range, it works in the setting frequency, isprotected and it always provides stable PWM pulse toLED driver.
