Block Diagram Description

The TPS6514x series offersa compact and small
power supply solutionto provide all three voltages
required by thin film transistor (TFT) LCD displays.
The auxiliary linear regulator controller can be used generatea 3.3-V logic power rail for systems
poweredbya 5-V supply rail only.
The main output VO1isa 1.6-MHz fixed frequency
PWM boost converter providing the source drive
voltagefor the LCD display. The deviceis availablein
two versions with different internal switch current
limitsto allow the useofa smaller external inductor
when lower output poweris required. The TPS65140
and TPS65141 hasa typical switch current limitof
2.3A and the TPS65145 hasa typical switch current
limitof 1.37A.A fully integrated adjustable charge
pump doubler or tripler provides the positive LCD
gate drive voltage. An externally adjustable negative
charge pump provides the negative gate drive
voltage. Dueto the high 1.6-MHz switching frequency the charge pumps, inexpensive and small 220-nF
capacitors canbe used.
Additionally, the TPS6514x series hasa system
power good outputto indicate when all supply rails
are acceptable. For LCD panels poweredby5V the
device hasa linear regulator controller using an
external transistorto providea regulated 3.3-V output
for the digital circuits. For maximum safety, the
TPS65140 and TPS65145 goes into shutdown as
soon as oneof the outputsis outof regulation. The
device can be enabled again by toggling the inputor
the enable (EN) pinto GND. The TPS65141 does not
enter shutdown when oneofits outputsis below its
power good threshold.
