7 V to 5.
8 V Boo st Converter Negative Charge Pu mp VO1 Up to 15 V / 350 mA VO2 Down to ±12 V / 20 mA 3 Description The TPS6510x series offers 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 device is available in two versions with different internal switch current limits to allow the use of a smaller external inductor when lower output power is required.
The TPS65100/01 has a typical switch current limit of 2.
3 A, and the TPS65105 has a typical switch current limit of 1.
37 A.
A fully integrated adjustable charge pump doubler/tripler provides the positive LCD gate drive voltage.
