MAX9550/MAX9551/MAX9552为TFT LCD提供一个VCOM驱动缓冲器。MAX9550/MAX9551/MAX9552可源出和吸收大电流，从而迅速恢复VCOM电压，非常适用于TFT LCD。输出能够在2µs内稳定到0.1%以内。此外，MAX9550/MAX9551/MAX9552可直接驱动TFT LCD中VCOM层的容性负载，而不需要串联电阻。

MAX9550/MAX9551/MAX9552分别为单通道、双通道和四通道VCOM放大器。MAX9550/MAX9551/MAX9552每通道可驱动高达800mA的峰值电流，电压最高20V。这些器件具有软启动功能，可降低浪涌电流，还提供输出短路保护和热关断功能。

MAX9550提供节省空间的5引脚SOT23封装，以及带有裸焊盘的8引脚µMAX®封装。MAX9551提供带有裸焊盘的8引脚µMAX封装。MAX9552提供14引脚TSSOP封装。所有器件额定工作在-40°C至+85°C温度范围。
