TRIPLE OUTPUT LCD SUPPLY WITH LINEAR REGULATOR AND POWER GOOD  
FEATURES  
DESCRIPTION  
•
•
•
•
2.7-V to 5.8-V Input Voltage Range  
1.6-MHz Fixed Switching Frequency  
3 Independent Adjustable Outputs  
The TPS65140/145 offers a compact and small  
power supply solution to provide 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.  
Main Output up to 15 V With <1% Typical  
Output Voltage Accuracy

Negative Output Voltage Down to -12 V/20 mA  
Positive Output Voltage up to 30 V/20 mA  
Auxiliary 3.3-V Linear Regulator Controller  
Internal Soft Start  
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 TPS65140  
has a typical switch current limit of 2.3 A and the  
TPS65145 has a typical switch current limit of 1.37 A.  
Internal Power-On Sequencing  
Fault Detection of all Outputs  
Thermal Shutdown  
A
fully integrated adjustable charge pump  
System Power Good  
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.  
Available in TSSOP-24 and QFN-24  
PowerPAD™ Packages

TFT LCD Displays for Notebooks  
TFT LCD Displays for Monitors  
Portable DVD Players  
Tablet PCs  
Car Navigation Systems  
Industrial Displays  
Additionally, the TPS65140/145 has a system power  
good output to indicate when all supply rails are  
acceptable. For LCD panels powered by 5 V, only the  
TPS65140/145 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 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.
