Description
The TPS65100-Q1 device 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 that provides the source-drive voltage for the LCD display. The TPS65100-Q1 has a typical switch current limit of 2.3 A. A fully integrated adjustable charge pump doubler-tripler provides the positive LCD gate-drive voltage. An externally adjustable negative charge pump provides the negative gate-drive voltage.
The TPS65100-Q1 has an integrated VCOM buffer to power the LCD backplane. For LCD panels powered by 5 V only, the TPS65100-Q1 device has a linear regulator controller using an external transistor to provide a regulated 3.3-V output for the digital circuits. For maximum safety, the TPS65100-Q1 device goes into shutdown as soon as one of the outputs is out of regulation. The device can be enabled again by toggling the input or the enable (EN) pin to GND.
