BD9478F Datasheet - ROHM

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.

BD9478F Features

* The signal that the frequency synchronizes with the

* VSYNC signal is output to PWMOUT. The PWM pulse is generated with the DC signal
