DESCRIPTION

DISCHARGE

The TPS65192 is a 9 channel level-shifter intended

for use in 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 signals used by the display panel.

The 9 level shifter channels are organized as two

groups. Channels 1 through 7 are powered from V_GH1

and V_GL, and channels 8 and 9 are powered from

V_GH2and V_GL. Each level-shifter channel features low

impedance output stages that achieve fast rise and

fall times even when driving the capacitive loading

typically present in LCD display applications.

Level shifter channels 1 through 6 support gate

voltage shaping, which can be used to improve

picture quality by reducing image sticking. Novel

decoding logic enables a single flicker clock signal to

control gate voltage shaping for all CLK channels

without the need for synchronization. The device also

supports the use of multiple flicker clocks. The rate of

decay is set by an external resistor or resistor

network connected to the RE pin.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas

Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of the Texas

Instruments standard warranty. Production processing does not

necessarily include testing of all parameters.
