Texas Instruments TPS65680RSNT

The TPS65680 device is a fullyprogrammable high-voltage level shifter solution for LCD panels. It supports up to twelvehigh-voltage clock outputs in either charge-sharing or gate-voltage shaping configuration and sixhigh-voltage control outputs for generating start, clear/reset, low-frequency ODD / EVEN signalsand panel discharge. The output timing is generated by the level shifter itself, based on auser-programmable pattern sequence and requires only two connections to the timing controller: aline clock and a start pulse that indicates the start of a new frame. These two signals can beshared between multiple TPS65680 devices in applications that require a higher number of outputchannels than one device can generate.

Customer-defined patterns and configuration settings can be stored in an on-chipnonvolatile memory to be usedas the default settings after power up. Alternatively, this data can be written to the device afterpower up, using the I²C interface. The programmability of theTPS65680 devicelets you change the output pattern without reprogramming or changing the TCON. Thus one PCB cansupport many different panels, which simplifies the system design, shortens the design cycle andenables economies of scale.
