General Description
The MAX1516/MAX1517/MAX1518 include a high-perfor-
mance step-up regulator, two linear-regulator controllers,
and high-current operational amplifiers for active-matrix
thin-film transistor (TFT) liquid-crystal displays (LCDs).
Also included is a logic-controlled, high-voltage switch
with adjustable delay.
The step-up DC-DC converter provides the regulated
supply voltage for the panel source driver ICs. The con-
verter is a high-frequency (1.2MHz) current-mode regu-
lator with an integrated 14V n-channel MOSFET that
allows the use of ultra-small inductors and ceramic
capacitors. It provides fast transient response to pulsed
loads while achieving efficiencies over 85%.
The gate-on and gate-off linear-regulator controllers
provide regulated TFT gate-on and gate-off supplies
using external charge pumps attached to the switching
node. The MAX1518 includes five high-performance
operational amplifiers, the MAX1517 includes three,
and the MAX1516 includes one operational amplifier.
These amplifiers are designed to drive the LCD back-
plane (VCOM) and/or the gamma-correction divider
string. The devices feature high output current
(±150mA), fast slew rate (13V/μs), wide bandwidth
(12MHz), and rail-to-rail inputs and outputs.
The MAX1516/MAX1517/MAX1518 are available in 32-
pin thin QFN packages with a maximum thickness of
0.8mm for ultra-thin LCD panels.
