Compact LCD Bias Supply For TFT-LCD TV Panels

The TPS65166 offers a compact power supply solution to provide all voltages required by a LCD panel for large TV panel applications running from a 12V supply rail. The device is optimized to support LCD technology using ASG Gate drive circuits. The device generates all voltage rails for the TFT LCD bias (V S , V ONE , V OFFE , V SS ). In addition to that it includes a Step-down converter (V Logic ) to provide the Logic voltage. By pulling the HVS pin high an implemented high voltage stress test feature programs the boost converter output voltage V s to higher values. The boost converter operates at a fixed switching frequency of 750kHz. The positive Charge Pump is running from the boost converter and is regulated by an external Transistor A buck-boost converter provides an adjustable temperature dependent negative output voltage V OFFE . The negative output voltage V SS is regulated by a shunt Regulator Safety features like overvoltage protection of the buck-boost input voltage, the boost and buck output voltage, undervoltage lockout, short Circuit Protection of V , V , and V are included as well as By Texas Instruments
