TRIPLE OUTPUT LCD SUPPLY WITH LINEAR REGULATOR AND VCOM BUFFER

FEATURES

DESCRIPTION

•

2.7-V to 5.8-V Input Voltage Range

1.6-MHz Fixed Switching Frequency

3 Independent Adjustable Outputs

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

Main Output of up to 15 V With < 1% Output

Voltage Accuracy

•

Virtual Sychronous Converter Technology

Negative Regulated Charge Pump Driver V_O2

Positive Charge Pump Converter V_O3

Integrated VCOM Buffer

The main output, V_O1, 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.

Auxiliary 3.3-V Linear Regulator Controller

Internal Soft Start

Internal Power-On Sequencing

Fault Detection of all Outputs (TPS65100/05)

No Fault Detection (TPS65101)

Thermal Shutdown

Available in TSSOP-24 and QFN-24

PowerPAD™ Packages

The TPS6510x series has an integrated VCOM

buffer to power the LCD backplane. For LCD panels

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.
