DESCRIPTION
The TPS65100/05 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.

TRIPLE OUTPUT LCD SUPPLY WITH LINEAR REGULATOR AND VCOM BUFFER
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
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
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 capaci-
tors can be used.

pump
The TPS65100/05 has an integrated VCOM buffer to
power the LCD backplane. For LCD panels powered
by 5 V only, the TPS65100/05 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 entire device goes into shut-
down 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.
