SLVSAC1 SEPTEMBER 2010  
LCD Bias Solution for Monitors  
Check for Samples: TPS65149  
The device integrates a boost converter to generate  
the source driver supply voltage (VAVDD), positive and  
negative charge pump controllers to generate gate

voltages,  
a
programmable VCOM generator, and an 8-channel  
level shifter in a single IC. The positive charge pump  
controller supports temperature compensation to  
reduce VGH at high temperatures.  
Selectable Switching Frequency (640 kHz or  
1.2 MHz)  
In addition to the above functions, the TPS65149  
generates two signals to discharge the display panel  
during power-down, plus an additional active-low  
XAO reset output.
