General Description
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
high-performance AV DD linear regulator, a positive
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 DD ). The two built-in charge-pump regulators
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
