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

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

the end of this data sheet.

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.
