General Description  
Features  
High-Performance Linear Regulator  
The MAX8710/MAX8711/MAX8712/MAX8761 offer com-  
plete linear-regulator power-supply solutions for thin-film  
transistor (TFT) liquid-crystal-display (LCD) panels used  
in LCD monitors and LCD TVs. All four devices include a

charge-pump regulator, a negative charge-pump regula-  
tor, and built-in power-up sequence control. The  
MAX8710/MAX8711/MAX8761 also include a high-cur-  
rent operational amplifier. Additionally, the MAX8710/  
MAX8761 provide logic-controlled high-voltage switches  
to control the positive charge-pump output.  
The linear regulator directly steps down the input voltage  
to generate the supply voltage for the source-driver ICs  
(AV ). The two built-in charge-pump regulators

12MHz, -3dB Bandwidth  
Rail-to-Rail Inputs/Output  
Dual-Mode™ High-Voltage Switches  
are used to generate the TFT gate-on and gate-off sup-  
plies. The high-current operational amplifier is typically  
used to drive the LCD backplane (VCOM) and features  
high output current (150mA), fast slew rate (12V/µs), and  
wide bandwidth (12MHz). Its rail-to-rail inputs and output  
maximize flexibility.  
The MAX8710/MAX8761 are available in a 24-pin thin  
QFN package, the MAX8711 is available in a 16-pin thin  
QFN package, and the MAX8712 is available in a 12-pin  
thin QFN package. All three packages are 4mm x 4mm  
with a maximum thickness of 0.8mm for ultra-thin LCD  
panel design. The MAX8710/MAX8711/MAX8712 oper-  
ate over the -40°C to +100°C temperature range and the  
MAX8761 operates over the -40°C to +85°C range.
