Internal-Switch Boost Regulator with Integrated
7-Channel Scan Driver, Op Amp, and LDO
General 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 adjust-

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