Low-Cost, Linear-Regulator

LCD Panel Power Supplies

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

linear regulator, a positive

♦ 50mA Negative Regulated Charge Pump

♦ 20mA Positive Regulated Charge Pump with

Adjustable Delay

♦ Built-In Power-Up Sequence

♦ High-Current Operational Amplifier

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.
