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. An externally adjustable negative
charge pump provides the negative gate drive
voltage. Due to the high 1.6-MHz switching frequency
of the charge pumps, inexpensive and small 220-nF
capacitors can be used.
The TPS6510x series has an integrated VCOM buffer
to power the LCD backplane. For LCD panels
powered by 5 V only, the TPS6510x series 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 TPS65100/05 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. The
TPS65101 does not enter shutdown when one of the
outputs is below its power good threshold.
