TPS65150 描述
The TPS65150 offers a very compact and small power supply solution that provides all three voltages required by thin film transistor (TFT) LCD displays. With an input voltage range of 1.8 V to 6.0 V the device is ideal for notebooks powered by a 2.5-V or 3.3-V input rail or monitor applications with a 5-V input voltage rail. Additionally the TPS65150 provides an integrated high current buffer to provide the VCOM voltage for the TFT backplane.
Two regulated adjustable charge pump driver provide the positive VGH and negative VGL bias voltages for the TFT. The device incorporates adjustable power on sequencing for VGL as well as for VGH. This avoids any additional external components to implement application specific sequencing
