Description
AI
The TPS65680 device is a fully programmable high-voltage level shifter solution for LCD panels. It supports up to twelve high-voltage clock outputs in either charge-sharing or gate-voltage shaping configuration and six high-voltage control outputs for generating start, clear/reset, low-frequency ODD / EVEN signals and panel discharge. The output timing is generated by the level shifter itself, based on a user-programmable pattern sequence and requires only two connections to the timing controller: a line clock and a start pulse that indicates the start of a new frame. These two signals can be shared between multiple TPS65680 devices in applications that require a higher number of output channels than one device can generate.
Customer-defined patterns and configuration settings can be stored in an on-chip nonvolatile memory to be used as the default settings after power up. Alternatively, this data can be written to the device after power up, using the I2C interface. The programmability of the TPS65680 device lets you change the output pattern without reprogramming or changing the TCON. Thus one PCB can support many different panels, which simplifies the system design, shortens the design cycle and enables economies of scale.
