MAX20070/MAX20070B  
Integrated TFT Power Supplies and  
LED Backlight Drivers  
General Description  
Benefits and Features  
● Integrates Both TFT Power Supplies and LED  
Backlight Driver in One IC, Reducing Component  
Count  
The MAX20070/MAX20070B are highly integrated  
power supplies and LED backlight drivers for automotive  
TFT-LCD applications. The devices integrate one buck-  
boost converter, one boost converter, two gate-driver  
supplies, and a boost/SEPIC converter that can power  
one to two strings of LEDs in the display backlight.  
● Alleviates EMI Due to Spread Spectrum on Both  
Source Driver Supplies and LED Driver  
● 10000:1 Dimming Ratio at 200Hz Dimming  
The source-driver power supplies consist of a boost  
converter and an inverting buck-boost converter that can  
generate voltages up to +15V and -15V. Both source-  
driver power supplies can deliver up to 100mA. The  
positive source-driver supply regulation voltage (V  
is set by connecting an external resistor-divider on FBP.  
Connecting the FBP pin to ground sets the regulation volt-

+50mV. The source-driver supplies use an input voltage  
from 2.7V to 5.5V to generate the output voltages.
