MAX1517ETJ-MAX1518ETJ
TFT-LCD DC-DC Converters with Operational Amplifiers
General DescriptionThe 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.

ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
