(TFT) LCD panel. With its high current capabilities, the device is ideal for large screen monitor panels and LCD

TV applications.

TYPICAL APPLICATION

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.

2PowerPAD is a trademark of Texas Instruments.

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.

This integrated circuit can be damaged by ESD. Texas Instruments recommends that all integrated circuits be handled with

appropriate precautions. Failure to observe proper handling and installation procedures can cause damage.

ESD damage can range from subtle performance degradation to complete device failure. Precision integrated circuits may be more

susceptible to damage because very small parametric changes could cause the device not to meet its published specifications.

DESCRIPTION (CONTINUED)

The device can be powered directly from a 12-V input voltage generating the bias voltages VGH and VGL, as

well as the source voltage V

and logic voltage for the LCD panels. The device consists of a boost converter to

provide the source voltage V

and a step-down converter to provide the logic voltage for the system. A positive

and a negative charge-pump driver provide adjustable regulated output voltages VGL and VGH to bias the TFT.

Both boost and step-down converters, as well as the charge-pump driver, operate with a fixed switching

frequency of 500 kHz or 750 kHz, selectable by the FREQ pin. The TPS65160 includes adjustable power-on

sequencing. The device includes safety features like overvoltage protection of the boost converter and short-

circuit protection of the buck converter, as well as thermal shutdown. Additionally, the device incorporates a gate

drive signal to control an isolation MOSFET switch in series with V

or VGH. See the application circuits at the

end of this data sheet.
