Description
The TPS65140-Q1 and TPS65145-Q1 devices offer acompact and small power supply solution that provides all three voltages required by thin-film transistor (TFT) LCD displays. The auxiliary linear
regulator controller can be used to generate a 3.3-V logic power rail for systems powered by a 5-V supply rail only.The main output, VO1 is a 1.6-MHz fixed-frequencyPWM boost converter providing the source-drive voltage for the LCD display. The TPS65140-Q1 device has a typical switch current limit of 2.3 A and the TPS65145-Q1 has a typical switch current limit of 1.37 A.A fully integrated adjustable charge pump doublerand provides the positive LCD gate-drive voltage. An externally adjustable negative charge pump provides the negative LCD gate-drive voltage.
