TPS65167A 具有完全集成的 正极充电泵、LDO 控制器、HVS (VDD/VGH) 和温度 传感器
TPS65167A 描述
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
