272RGB x 480 TFT LCD Driver
Integrated Power Circuit, Gate and Source Driver

SSD2125 is an all in one driver that integrated the power circuits, gate driver and source driver into single chip. It can drive a 16.7M/262k/8 color a-TFT panel with resolution of 272 RGB x 480.

SSD2125 embeds DC-DC Converter and Voltage generator to provide all necessary voltage required by the driver with minimum external components. A Common Voltage Generation Circuit is included to drive the TFT-display counter electrode. An Integrated Gamma Control Circuit is also included that can be adjusted by software commands to provide maximum flexibility and optimal display quality.

SSD2125 can be operated down to 1.6V and provide different power save modes. It is suitable for any portable battery-driven applications requiring long operation period with compact size.
