The TPS65167 offers a compact power supply soluTIon to provide all voltages required by a LCD panel for large size monitor and TV panel applicaTIons running from a 12-V supply rail.
The device generates all 3 voltage rails for the TFT LCD bias (Vs, VGL and VGH). In addiTIon to that it includes a step-down converter and a LDO controller to provide two logic voltage rails. The device incorporates a high voltage switch that can be controlled by a logic signal from the external TIming controller (TCON). This function allows gate voltage shaping for VGH. The device also features a high voltage stress test where the output voltage of VGH is set to typically 30 V and the output voltage of Vs is programmable to any higher voltage.
