BD9478F - PWM pulse Generator

BD9478F is PWM pulse generator for LCD panel.

This IC compares triangle waveform which is generated inside IC and external DC signal, and generates a PWM pulse.

This PWM pulse is provided to LED driver and controls LED grayscale.

PWM pulse frequency can be synchronized to external signal frequency i
