TPS65150PWPR Low Input Voltage, Compact LCD Bias IC linear digital integrated circuits

APPLICATIONS

• TFT LCD Displays for Notebook]

• TFT LCD Display for Monitor

• Car Navigation Display

DESCRIPTION

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 thedevice 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 theVCOM voltage for the TFT backplane.

Two regulated adjustable charge pump driver provide the positive VGH and negative VGL bias voltages forthe 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. The device has an integrated high voltage switch to isolate VGH.
