Texas Instruments TPS65175 Fully Programmable LCD Bias IC for GIP TV with Integrated 12-Ch Level Shifters and 6-Ch Gamma Buffer TPS65175RSHR

The TPS65175RSHR is a fully programmable LCD bias integrated circuit designed for GIP TV applications. It operates within an input voltage range of 8.6V to 14.7V and features a boost converter with a programmable output voltage of 12.7V to 19V. The device includes a buck converter that tracks the V_{DD} voltage and provides outputs of 1.6V to 2.0V and 3.0V to 3.6V. Additionally, it incorporates a positive charge pump for generating V_{GH} voltages ranging from 19V to 34V at low temperatures and 17V to 32V at high temperatures, as well as a negative charge pump for V_{GL} from -1.8V to -8.1V. The TPS65175RSHR integrates a 6-channel gamma buffer and a 12-channel level shifter, supporting both forward and reverse operations with abnormal operation detection. Programmable features include output voltage levels, sequencing delays, and temperature compensation for V_{GH} and V_{COM}. The device is housed in a compact 7mm x 7mm QFN package, making it suitable for various LCD bias applications, including TFT-LCD panels and monitors.
