BD9478F Datasheet - ROHM

PWM pulse Generator

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

BD9478F General Description

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.
