Texas Instruments TPS65680RSNT 18-Channel Configurable Level Shifter is a fully programmable high-voltage level shifter solution for LCD panels. This device 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 TPS65680RSNT devices in applications that require a higher number of output channels than one device can generate.
