3 Description

The TPS65150 device 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 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 device

provides an integrated high current buffer to provide

the VCOM voltage for the TFT backplane.
