SLVSE46A – NOVEMBER 2017 – REVISED JANUARY 2018 TPS65680 18-Channel Pattern-Programmable Level Shifter with Overcurrent Protection
1 Features 3 Description The TPS65680 device is a fully programmable highvoltage 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. Programmable Output Pattern
