TPS6510x
2.7 V to 5.8 V
SLVS496C – SEPTEMBER 2003 – REVISED APRIL 2006
TRIPLE OUTPUT LCD SUPPLY WITH LINEAR REGULATOR AND VCOM BUFFER
2.7-V to 5.8-V Input Voltage Range
The TPS6510x series offers a compact and small
power supply solution that provides all three voltages
1.6-MHz Fixed Switching Frequency
required by thin film transistor (TFT) LCD displays.
3 Independent Adjustable Outputs
The auxiliary linear regulator controller can be used
Main Output of up to 15 V With < 1% Output
to generate a 3.3-V logic power rail for systems
Voltage Accuracy
powered by a 5-V supply rail only.
Virtual Sychronous Converter Technology
The main output, VO1, is a 1.6-MHz, fixed-frequency
Negative Regulated Charge Pump Driver VO2
PWM boost converter providing the source drive
voltage for the LCD display. The device is available
Positive Charge Pump Converter VO3
in two versions with different internal switch current
Integrated VCOM Buffer

The
TPS65100/01 has a typical switch current limit of 2.3
Internal Soft Start
A, and the TPS65105 has a typical switch current
Internal Power-On Sequencing
limit of 1.37 A. A fully integrated adjustable charge
Fault Detection of all Outputs (TPS65100/05)
pump doubler/tripler provides the positive LCD gate
drive voltage. An externally adjustable negative
No Fault Detection (TPS65101)
charge pump provides the negative gate drive

Due
to
the
high
1.6-MHz
switching
Available in TSSOP-24 and QFN-24
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
TFT LCD Displays for Notebooks
powered by 5 V only, the TPS6510x series has a
TFT LCD Displays for Monitors
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

regulation. The device can be enabled again by
Industrial Displays
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.
