LCD Power Supplies for Notebooks MAX17117



Internal-Switch Boost Regulator with Integrated

 7-Channel Scan Driver, Op Amp, and LDO


The MAX17117 Is a Highly Integrated Solution Suitable to Drive GOA/GIP 
Notebook LCD Panels



Description

The MAX17117 includes a high-performance step-up regulator, a 350mA low-dropout (LDO) linear regulator,
 a high-speed operational amplifier,
 and a high-voltage level-shifting scan driver with gate-shading control. The device is optimized for thin-film
transistor (TFT) liquid-crystal display (LCD) applications.

The step-up DC-DC converter provides the regulated supply voltage for panel source-driver ICs. The high
1.2MHz switching frequency allows the use of ultra-small inductors and ceramic capacitors. The current-mode
control architecture provides a fast-transient response to pulsed loads typical of source driver loads. The step-up
 regulator features an adjustable soft-start and an adjustable cycle-by-cycle current limit.

The high-current operational amplifier is designed to drive the LCD backplane (VCOM). The amplifier features
high output current (±200mA typ), fast slew rate (40V/µs typ), wide bandwidth (16MHz typ), and rail-to-rail inputs
and outputs.

The low-voltage LDO linear regulator has an integrated 0.8Ω pass element and can provide at least 350mA. The
output voltage is accurate within ±1%.

The high-voltage, level-shifting scan driver with gate-shading control is designed to drive the TFT panel gate
drivers. Its seven outputs swing 40V (maximum) between +35V (maximum) and -15V (minimum) and can swiftly
drive capacitive loads.

The MAX17117 is available in a 32-pin, 5mm x 5mm, thin QFN package with a maximum thickness of 0.8mm for
thin LCD panels.
