MAX8710, MAX8711 pdf datasheet

The MAX8710/MAX8711/MAX8712/MAX8761 offer complete
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 AVDD linear regulator, a positive
charge-pump regulator, a negative charge-pump regulator,
and built-in power-up sequence control. The
MAX8710/MAX8711/MAX8761 also include a high-current
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
(AVDD). The two built-in charge-pump regulators
are used to generate the TFT gate-on and gate-off supplies.
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 operate
over the -40°C to +100°C temperature range and the
MAX8761 operates over the -40°C to +85°C range.
