The TPS65140-Q1 and TPS65145-Q1 devices offer a compact 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-frequency PWM 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 doubler and provides the positive LCD gate-drive voltage. An externally adjustable negative charge pump provides the negative LCD gate-drive voltage.

For compensation of the devices please refer to Application Note: How to Compensate with the TPS6510x and TPS6514x SLVA813.
