LCD面板用PWM信号生成器

BD9478F是LCD面板用PWM信号生成器。此IC通过对IC内部产生的三角波与外部DC信号进行比较,生成PWM信号。此PWM信号提供给LED驱动器,对LED调光进行控制。PWM脉冲频率与输入到SYNC端子的外部信号频率同步。当此频率超过规定范围时,则在设定频率内动作以进行保护,并常时向LED驱动器提供稳定的PWM脉冲。 ・ The signal that the frequency synchronizes with the VSYNC signal is output to PWMOUT. \n・ The PWM pulse is generated with the DC signal of a triangular wave and PDIM generated with the LCT capacitor. \n・ When the VSYNC frequency exceeds the stipulated range, it fixes by a set frequency.
