10-Channel Level Shifter and VCOM Buffer

The uncommitted high-speed operational amplifier

features a high slew rate and high peak current

capability that make it particularly suitable for driving

the panel’s common rail (V_COM).

DESCRIPTION

The TPS65190 is

combined multi-channel

level-shifter and V_COMbuffer intended for use in large

format LCD display applications such as TVs and

monitors. The device converts the logic-level signals

generated by the Timing Controller (T-CON) to the

high-level gate drive signals used by the display

panel and amplifies/buffers an externally generated

V_COMvoltage.

IN8

The 10 level shifter channels are organized as 2

groups, each with its own positive supply. Channels

1-6 and 9-10 are supplied by V_GH1and channels 7-8

are supplied by V_GH2. The two positive supplies can

be tied together if one positive supply voltage is used

for all level shifter channels. Both level shifter groups

use the same negative supply V_GL.

The level-shifters feature low impedance output

stages that achieve fast rise and fall times even when

driving significant capacitive loads.
