DESCRIPTION
The TPS65190 is a combined multi-channel
level-shifter and VCOM buffer 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
VCOM voltage.
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 VGH1 and channels 7-8
are supplied by VGH2. 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 VGL.
The level-shifters feature low impedance output
stages that achieve fast rise and fall times even when
driving significant capacitive loads.
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 (VCOM).
